  The first change in the data and metadata message is one of terminology. In order to foster consistency in the standard, the names and namespaces of the data and metadata message have been changed. The namespaces now have a uniform format of /data/format and /metadata/format, where format is either generic or structured (i.e. the structure specific formats). This also applies to the message names as well, where the names follow the pattern of FormatData (e.g. StructuredData and GenericMetadata).
--The various data messages which existed in the standard have been harmonised into two general formats; generic and structured data. The generic data is much like it has been previously, only slightly modified to conform with the harmonised view on data. The structured data combined the principles of the previous versions compact and cross sectional formats into one more generalised format.

The structured data combined the principles of the previous (% style="color:#e74c3c" %)versions(%%) compact and cross sectional formats into one more generalised format.
--The major shift from the previous version is now that all data can be exchanged as either an un-grouped collection of observations, each specifying a full key or it can be exchanged as data grouped into series with any single dimension placed at the observation level. This in effect, combined the abilities of the time series and cross sectional formats in the a single data format. This format also allows for multiple measure to be expressed when the observation dimension is the measure dimension defined in the data structured. The key differences from the previous versions is that this all is possible in a single data structure definition specific format, as well as being possible in the generic format as well. The goal was to make the structures as homogenous as possible.

This in effect, combined the abilities of the time series and cross sectional formats in the a single data format. This format also allows for multiple [[measure>>doc:sdmx:Glossary.Measure.WebHome]] to be expressed when the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is the [[measure>>doc:sdmx:Glossary.Measure.WebHome]] [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] defined in the data structured.

The goal was to make the structures as homogenous as possible.
--Another shift from the previous version in the manner in which the base data structure specific format is defined. In previous versions there was not structure defined, so one had to understand all of the requirements and read the specification in order to understand what could be expected in any structure specific format. In this version, that issue has been addressed. The base structures now impose a strict format on the data structure specific schemas. This is achieved much like the referencing structure in the common namespace through the use of unqualified elements. By the elements not existing in a namespace, the structure specific schemas can place the necessary restrictions of them while still being forced to adhere to prescribed structure. This means that not only are the structures able to perform the validation that is required, but that the messages will be much simpler to process as the format will always use the same element names.

--Finally, in order to allow for systems which wish to not process the new more flexible data format, time series only variations of both the generic and structured data sets exist. It is important to note that these structures are derived via restriction from the more generalised format. This means that a data set in the general format with the time dimension at the observation level will have exactly the same content as a time series only data set. The result of this is that there is no additional burden for processing the time series specific format it a system can process the more generalised format. These time series only data sets allow for time series only data messages to exist. These messages make it simple for system which, in the previous version of the standard, only used the time series formats to continue to do so.

--These same principles have been applied to the reference data messages as well. In the previous version of the standard there were major differences between the generic and metadata structure-specific formats; some of the differences caused some metadata sets were incompatible between versions. In this version the structures of the generic and metadata structure specific formats have been harmonised to the point where they are nearly identical. Yet, the structured format still provides the strong validation against the metadata structure that is intended. And, as with the data, the base metadata structure specific format now imposes a stricter structure on the generated schemas, making the structure specific instance simpler to process in a generic manner.

--**DataSetType: **DataSetType defines the structure of the generic data set. Data is organised into either a collection of series (grouped observations) or a collection of un-grouped observations. The organisation used is dependent on the structure specification in the header of the data message (which is referenced via the structureRef attribute). The structure specification states which data occurs at the observation level. If this dimension is "AllDimensions" then the data set must consist of a collection of un-grouped observations; otherwise the data set will contain a collection of series with the observations in the series disambiguated by the specified dimension at the observation level. This data set is capable of containing data (observed values) and/or documentation (attribute values). It is assumed that each series or un-grouped observation will be distinct in its purpose. For example, if series contains both data and documentation, it assumed that each series will have a unique key. If the series contains only data or only documentation, then it is possible that another series with the same key might exist, but with not with the same purpose (i.e. to provide data or documentation) as the first series.

--**//DataSetType//: **DataSetType is the abstract type which defines the base structure for any data structure definition specific data set. A derived data set type will be created that is specific to a data structure definition and the details of the organisation of the data (i.e. which dimension is the observation dimension and whether explicit measures should be used). Data is organised into either a collection of series (grouped observations) or a collection of un-grouped observations. The derived data set type will restrict this choice to be either grouped or un-grouped observations. If this dimension is "AllDimensions" then the derived data set type must consist of a collection of un-grouped observations; otherwise the data set will contain a collection of series with the observations in the series disambiguated by the specified dimension at the observation level. This data set is capable of containing data (observed values) and/or documentation (attribute values) and can be used for incremental updates and deletions (i.e. only the relevant updates or deletes are exchanged). It is assumed that each series or un-grouped observation will be distinct in its purpose. For example, if series contains both data and documentation, it assumed that each series will have a unique key. If the series contains only data or only documentation, then it is possible that another series with the same key might exist, but with not with the same purpose (i.e. to provide data or documentation) as the first series. This base type is designed such that derived types can be processed in a generic manner; it assures that data structure definition specific data will have a consistent structure. The group, series, and observation elements are unqualified, meaning that they are not qualified with a namespace in an instance. This means that in the derived data set types, the elements will always be the same, regardless of the target namespace of the schemas which defines these derived types. This allows for consistent processing of the structure without regard to what the namespace might be for the data structure definition specific schema. The data set can contain values for attributes which do not have an attribute relationship with any data structure definition components. These attribute values will exist in XML attributes in this element based on this type (DataSet). This is specified in the content model with the declaration of anyAttributes in the "local" namespace. The derived data set type will refine this structure so that the attributes are explicit. The XML attributes will be given a name based on the attribute's identifier. These XML attributes will be unqualified (meaning they do not have a namespace associated with them). To allow for generic processing, it is required that the only unqualified XML attributes in the derived data set type (outside of the standard data set attributes) be for attributes declared in the data structure definition. If additional attributes are required, these should be qualified with a namespace so that a generic application can easily distinguish them as not being meant to represent a data structure definition attribute.

--|dataScope|DataScopeType|The dataScope attribute indicates the scope at which the data is meant to be validated. These scopes are hierarchical and are (from the top down); DataStructure, ConstrainedDataStructure, Dataflow, and ProvisionAgreement. the hierarchy of these scopes represent the cascading level of constraints, which can restrict the valid values for components. For example, a data structure defines a dimension with a coded representation. A data flow might have a constraint associated with it which further restricts the values allowed from the referenced code list to a subset of the values allowed by the data structure definition. A provision agreement that is based on the dataflow might also have a constraint, which further restricts the subset of the codelist from the dataflow. Therefore, the allowed content becomes stricter lower in the hierarchy. Data that is given a scope of one value is stated to be valid at that level and all levels below it. Therefore, this scope serves to state that data that is meant to be structured simply against the data structure definition is not meant to be validated against the a dataflow, where constraints might be applied.
--|REPORTING_YEAR_START_DAY|xs:gMonthDay|The REPORTING_YEAR_START_DAY attribute is an explict attribute for the reporting year start day, which provides context to the time dimension when its value contains a reporting period (e.g. 2010-Q1). This attribute is used to state the month and day that the reporting year begins (e.g. ~-~-07-01 for July 1st). In the absence of an explicit value provided in this attribute, all reporting period values will be assumed to be based on a reporting year start day of January 1. This is declared in the base schema since it has a fixed identifier and representation. The derived data set type may either require or prohibit this attribute, depending on whether the data structure declared the reporting year start day attribute and if so, the attribute relationship and assignment status assigned to it.

--**//GroupType//: **GroupType is the abstract type which defines a structure which is used to communicate attribute values for a group defined in a data structure definition.

--**//TimeSeriesDataSetType//: **TimeSeriesDataSetType is the abstract type which defines the base structure for any data structure definition specific time series based data set. A derived data set type will be created that is specific to a data structure definition. Unlike the base format, only one variation of this is allowed for a data structure definition. This variation is the time dimension as the observation dimension. Data is organised into a collection of time series. Because this derivation is achieved using restriction, data sets conforming to this type will inherently conform to the base data set structure as well. In fact, data structure specific here will be identical to data in the base data set when the time dimension is the observation dimension, even for the derived data set types. This means that the data contained in this structure can be processed in exactly the same manner as the base structure.

--|dataScope|DataScopeType|The dataScope attribute indicates the scope at which the data is meant to be validated. These scopes are hierarchical and are (from the top down); DataStructure, ConstrainedDataStructure, Dataflow, and ProvisionAgreement. the hierarchy of these scopes represent the cascading level of constraints, which can restrict the valid values for components. For example, a data structure defines a dimension with a coded representation. A data flow might have a constraint associated with it which further restricts the values allowed from the referenced code list to a subset of the values allowed by the data structure definition. A provision agreement that is based on the dataflow might also have a constraint, which further restricts the subset of the codelist from the dataflow. Therefore, the allowed content becomes stricter lower in the hierarchy. Data that is given a scope of one value is stated to be valid at that level and all levels below it. Therefore, this scope serves to state that data that is meant to be structured simply against the data structure definition is not meant to be validated against the a dataflow, where constraints might be applied.

  Data structure and metadata structure-specific schemas are each based on one single core construct found in their respective structure-specific namespaces;
--Data  - http:~/~/www.SDMX.org/resources/SDMXML/schemas/v2_1/data/structurespecific
++Data - http:~/~/www.SDMX.org/resources/SDMXML/schemas/v2_1/data/structurespecific
  Metadata - http:~/~/www.SDMX.org/resources/SDMXML/schemas/v2_1/data/structurespecific
  For a metadata structure, only a single schema will be created for the entire structure definition. For data structures, many variations of the base schema are possible, each specific as to how the data is organised. This will be discussed in more details in the specific rules for the data structure schemas.

  It is assumed that in order to use this guide, the reader is familiar with schema terminology. However, for convenience the following is list of the terminology used here:
  **Schema:** Refers to the format specific schema in general, and in particular the root xs:schema element of that schema file.
--**Global Element:** Refers to an element definition at the top level of the schema (i.e. an xs:element element in the root xs:schema element). It will define a name and type (name and type attributes) and possibly a substitution group (substitutionGroup attribute).
++**Global Element:** Refers to an element definition at the top (% style="color:#e74c3c" %)level(%%) of the schema (i.e. an xs:element element in the root xs:schema element). It will define a name and type (name and type [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]) and possibly a substitution group (substitutionGroup [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
--**Local Element:** Refers to an element definition within a complex type (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element). A local element must define a name and type (name and type attributes) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs attribute).
++**Local Element:** Refers to an element definition within a complex type (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element). A local element must define a name and type (name and type [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
  **Qualified/Unqualified Element:** A qualified element is an element that must be referred to by the namespace in which it was defined. An unqualified element does not have a namespace associated with it. The structure specific schemas make use of unqualified elements to that the structure specific schemas can restrict the base content to meet the specific needs of the structure, while maintaining as much of the original document structure as possible.
--**Element Reference:** Refers to an element definition within a complex type that is a reference to a global element (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element). An element reference must reference a global element (via its ref attribute) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs attribute).
++**Element Reference:** Refers to an element definition within a complex type that is a reference to a global element (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element). An element reference must reference a global element (via its ref [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
--**Complex Type:** Refers to a complex type definition. In this context, all complex type definitions occur at the top level of the schema (i.e. an xs:complexType element in the root xs:schema element). A complex type must define a name (name attribute) and may be made abstract (via the abstract attribute’s boolean value).
++**Complex Type:** Refers to a complex type definition. In this context, all complex type definitions occur at the top (% style="color:#e74c3c" %)level(%%) of the schema (i.e. an xs:complexType element in the root xs:schema element). A complex type must define a name (name [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]) and may be made abstract (via the abstract [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]’s boolean value).
--**Simple Type:** Refers to a simple type definition. In this context, all simple type definitions occur at the top level of the schema (i.e. an xs:simpleType element in the root xs:schema element). In this context, a simple type will always be defined via a restriction (an xs:restriction element in the xs:simpleType element). The restriction will reference a base type.
++**Simple Type:** Refers to a simple type definition. In this context, all simple type definitions occur at the top (% style="color:#e74c3c" %)level(%%) of the schema (i.e. an xs:simpleType element in the root xs:schema element). In this context, a simple type will always be defined via a restriction (an xs:restriction element in the xs:simpleType element). The restriction will reference a base type.
  **Anonymous Type:** A complex or simple type definition which occurs within an element definition. The method is sometimes referred to a the "Russian-doll" technique as it creates nested constructs. Anonymous types are not given names and cannot be abstract. The can however, be derived from other types.
  **Content Group:** A group which defines a content model for reuse. This is contained in the xs:group element, and is defined at the root of the schema. It allows for a common sequence or choice of elements to be reused across multiple types without having to redefine the sequence or choice in each type.
--**Uniqueness Constraint:** A uniqueness constraint is defined within an element and is used to force descendent elements to be unique based on some criteria of it fields (elements or attributes). This is defined in an <xs:unique> element, and has content of an <xs:selector> and multiple <xs:field> elements. The selector designates the descendants that must be unique (with an xpath attribute) and the field specifies which property of the selected element must be unique (also with an xpath attribute)
++**Uniqueness (% style="color:#e74c3c" %)Constraint(%%):** A uniqueness (% style="color:#e74c3c" %)constraint(%%) is defined within an element and is used to force descendent elements to be unique based on some criteria of it fields (elements or [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]). This is defined in an element, and has content of an and multiple elements. The selector designates the descendants that must be unique (with an xpath [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]) and the field specifies which property of the selected element must be unique (also with an xpath [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]])
--**Extension:** Refers to the definition of a complex type that is an extension of another complex type. The extension will always make a reference to a base. In the schema, this is defined within the xs:complexType element as a child xs:complexContent element containing an xs:extension element (with a base attribute).
++**Extension:** Refers to the definition of a complex type that is an extension of another complex type. The extension will always make a reference to a base. In the schema, this is defined within the xs:complexType element as a child xs:complexContent element containing an xs:extension element (with a base [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
--**Restriction:** Refers to the definition of a simple or complex type that is a restriction of another type of the same variety. The restriction will always make a reference to a base. In the schema, this is defined with an xs:restriction element (with a base attribute).
++**Restriction:** Refers to the definition of a simple or complex type that is a restriction of another type of the same variety. The restriction will always make a reference to a base. In the schema, this is defined with an xs:restriction element (with a base [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
--**Sequence:** Refers to a sequence of elements that may be defined as the root of a complex type content model, or as part of the content of a choice or another sequence. This is defined as an xs:sequence element. The sequence may specify a minimum and maximum occurrence (minOccurs and maxOccurs attribute).
++**Sequence:** Refers to a sequence of elements that may be defined as the root of a complex type content model, or as part of the content of a choice or another sequence. This is defined as an xs:sequence element. The sequence may specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
--**Choice:** Refers to a choice of elements that may be defined as the root of a complex type content model, or as part of the content of a sequence or another choice. This is defined as an xs:choice element. The sequence may specify a minimum and maximum occurrence (minOccurs and maxOccurs attribute).
++**Choice:** Refers to a choice of elements that may be defined as the root of a complex type content model, or as part of the content of a sequence or another choice. This is defined as an xs:choice element. The sequence may specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
--**Facet:** Refers to a single detail of a simple type restriction. This is represented by elements such as xs:minInclusive, xs:totalDigits, xs:minLength, and is contained in the xs:restriction element of a simple type definition. The value of the facet is contained in a value attribute of the particular element.
++**[[Facet>>doc:sdmx:Glossary.Facet.WebHome]]:** Refers to a single detail of a simple type restriction. This is represented by elements such as xs:minInclusive, xs:totalDigits, xs:minLength, and is contained in the xs:restriction element of a simple type definition. The value of the [[facet>>doc:sdmx:Glossary.Facet.WebHome]] is contained in a value [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] of the particular element.
--**Enumeration:** Refers to an enumerated value of a simple type definition. It is represented by an xs:enumeration element contained within an xs:restriction element of a simple type definition. An enumeration defines a value (in the value attribute) and documentation (in xs:documentation elements contained in an xs:annotation element).
++**Enumeration:** Refers to an enumerated value of a simple type definition. It is represented by an xs:enumeration element contained within an xs:restriction element of a simple type definition. An enumeration defines a value (in the value [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]) and documentation (in xs:documentation elements contained in an xs:[[annotation>>doc:sdmx:Glossary.Annotation.WebHome]] element).
--**XML Attribute:** Refers to the definition of an XML attribute for a complex type (i.e. and xs:attribute element in a xs:complexType element). An attribute must define a name and type (name and type attributes) and may also specify a usage (use attribute).
++**XML [[Attribute>>doc:sdmx:Glossary.Attribute.WebHome]]:** Refers to the definition of an XML [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] for a complex type (i.e. and xs:[[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] element in a xs:complexType element). An [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] must define a name and type (name and type [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]) and may also specify a usage (use [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).

--11. Namespace Rules
++== 3.2 Namespace Rules ==
--Each format specific schema will specify its namespace in the target namespace of the schema (the targetNamespace attribute of the schema). This document also assumes that the root namespace (that which is defined by the xmlns attribute) of the schema will be the same as the target namespace. Therefore any types or global elements referenced in these descriptions without a namespace prefix are assumed to be in the format specific namespace.
++Each format specific schema will specify its namespace in the target namespace of the schema (the targetNamespace [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] of the schema). This document also assumes that the root namespace (that which is defined by the xmlns [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]) of the schema will be the same as the target namespace. Therefore any types or global elements referenced in these descriptions without a namespace prefix are assumed to be in the format specific namespace.
  The format specific schemas will incorporate the core format namespace and the common namespace by importing the schemas (via the xs:import element). If necessary, additional namespaces may be imported and referenced.
--For the purpose of the descriptions here, the default element form for the schema (as specified in the elementFormDefault attribute of the schema) is “qualified", and the default attribute form (as specified in the attributeFormDefault attribute of the schema) is "unqualified".
++For the purpose of the descriptions here, the default element form for the schema (as specified in the elementFormDefault [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] of the schema) is “qualified", and the default [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] form (as specified in the attributeFormDefault [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] of the schema) is "unqualified".

--11. General Rules
++== 3.3 General Rules ==
  The following section details the general rules which apply to all structure specific schema creation.
--1.
--11.
--111. Component Name Determination
++=== 3.3.1 Component Name Determination ===
--When required to create an XML element or attribute, the name for a component is always its identifier. However, the identifier may be inherited. Therefore, the general rules is as follows:
++When required to create an XML element or [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]], the name for a [[component>>doc:sdmx:Glossary.Component.WebHome]] is always its identifier. However, the identifier may be inherited. Therefore, the general rules is as follows:
--1. If the component defines an identifier, the element or attribute name is the value of that identifier
--1. Otherwise, the element or attribute name is the identifier of the concept from which it takes its semantic (Note that this is technically the component identifer).
--11.
--111. Representation Determination
++1. If the [[component>>doc:sdmx:Glossary.Component.WebHome]] defines an identifier, the element or [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] name is the value of that identifier
++1. Otherwise, the element or [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] name is the identifier of the (% style="color:#e74c3c" %)concept(%%) from which it takes its semantic (Note that this is technically the [[component>>doc:sdmx:Glossary.Component.WebHome]] identifer).
--Every component has a representation associated with it, whether it is defined as a local representation in the component definition, or it is inherited from the concept from which the component takes it semantic (as defined in the concept identity of the component).
++=== 3.3.2 Representation Determination ===
--The representation of a component is determined by the following precedence:
++Every [[component>>doc:sdmx:Glossary.Component.WebHome]] has a [[representation>>doc:sdmx:Glossary.Representation.WebHome]] associated with it, whether it is defined as a local [[representation>>doc:sdmx:Glossary.Representation.WebHome]] in the [[component>>doc:sdmx:Glossary.Component.WebHome]] definition, or it is inherited from the (% style="color:#e74c3c" %)concept(%%) from which the [[component>>doc:sdmx:Glossary.Component.WebHome]] takes it semantic (as defined in the (% style="color:#e74c3c" %)concept(%%) identity of the [[component>>doc:sdmx:Glossary.Component.WebHome]]).
--1. The local representation defined by the component
--1. The core representation defined in the concept from which the component takes its semantic
--1. A default representation of an un-faceted text format with a data type of String.
++The [[representation>>doc:sdmx:Glossary.Representation.WebHome]] of a [[component>>doc:sdmx:Glossary.Component.WebHome]] is determined by the following precedence:
--The representation will either define a text format, or an enumeration with an enumeration format.
++1. The local [[representation>>doc:sdmx:Glossary.Representation.WebHome]] defined by the [[component>>doc:sdmx:Glossary.Component.WebHome]]
++1. The core [[representation>>doc:sdmx:Glossary.Representation.WebHome]] defined in the (% style="color:#e74c3c" %)concept(%%) from which the [[component>>doc:sdmx:Glossary.Component.WebHome]] takes its semantic
++1. A default [[representation>>doc:sdmx:Glossary.Representation.WebHome]] of an un-faceted text format with a data type of String.
--A text format consists of a data type and an optional collection of facets. It is the combination of these which determine the exact nature of the component representation. An enumeration consists of a reference to an item scheme, for which an enumerated list of possible values can be created.
++The [[representation>>doc:sdmx:Glossary.Representation.WebHome]] will either define a text format, or an enumeration with an enumeration format.
--1.
--11.
--111. Simple / Primitive Type Determination
++A text format consists of a data type and an optional collection of [[facets>>doc:sdmx:Glossary.Facet.WebHome]]. It is the combination of these which determine the exact nature of the [[component>>doc:sdmx:Glossary.Component.WebHome]] [[representation>>doc:sdmx:Glossary.Representation.WebHome]]. An enumeration consists of a reference to an [[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]], for which an enumerated list of possible values can be created.
--For any given representation, there exist rules for determining the simple or primitive type which should be used to validate the value. There are no specific requirements to how a simple type is named or if it is referenced or used as an anonymous type. This section simply serves to state the requirements of the type for a component based on its [[determined representation>>path:#_Representation_Determination:]].
++=== 3.3.3 Simple / Primitive Type Determination ===
--For example, a dimension may inherit its representation for a concept, and the data type of a representation data type may be a String. The simplest solution would be to use the xs:string primitive type. However, an implementer may have chosen to generate simple types for all concepts to avoid having to look up the concept core representation for very component. In this case, the type may be given a name based on the concept and be a simple derivation from the xs:string type that places no further restrictions. The result would be that the type that is actually used for the dimension, although named after the concept, is effectively the required xs:string. These rules are meant to allow such flexibility in how types are created. The only requirement is that the type meet the requirements stated here.

++For example, a [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] may inherit its [[representation>>doc:sdmx:Glossary.Representation.WebHome]] for a (% style="color:#e74c3c" %)concept(%%), and the data type of a [[representation>>doc:sdmx:Glossary.Representation.WebHome]] data type may be a String.

These rules are meant to allow such flexibility in how types are created. The only requirement is that the type meet the requirements stated here.
--A representation which defines an enumeration will result in a simple type that is a restriction of the common:IDType. The simple type will define enumerations for each item in the item scheme. The value for these enumerations will be identifier of the item. If desired, the names of the item may be placed in the documentation of the enumeration, but this is not required. Example:
++=== 3.3.4 Representation with Enumeration ===
++A [[representation>>doc:sdmx:Glossary.Representation.WebHome]] which defines an enumeration will result in a simple type that is a restriction of the common:IDType.

If desired, the names of the item may be placed in the documentation of the enumeration, but this is not required. Example:

--111. Representation with Text Format
++These rules will only dictate type names where absolutely necessary. In all other cases, it is the decision of the implementer as to how to name or use the type. It is also the implementer's requirement to ensure that any type name is properly unique within its scope. To assist in this, the following recommendations are offered for naming types such that they are unique.
--A representation which defines a text format will result in a simple type or primitive type. The first step is to determine the base type from the text format data type:

--If the text format does not specify any further facets, then the determined type is the listed type or a type which derives from the listed type without placing any addition restrictions on it. However, if one or more facets are specified, then a simple type based on the listed type is necessary. The simple type derives via restriction from the listed type and adds facets according to the following table (the values are mapped as is):

++Only the constructs that will be detailed in the data and metadata structure-specific rules below are required to be in the specified target namespace of the structure-specific schema. So long as any other generated type conforms to the rules specified, it may exist in any namespace.
--These rules will only dictate type names where absolutely necessary. In all other cases, it is the decision of the implementer as to how to name or use the type. It is also the implementer's requirement to ensure that any type name is properly unique within its scope. To assist in this, the following recommendations are offered for naming types such that they are unique.

--* It the type is an enumeration from an item scheme, the recommended name is [Item Scheme Class].[Maintenance Agency].[Item Scheme ID].[Item Scheme Version]
--* If the type is based on a text format of a concept core representation, the recommended name is Concept.[Maintenance Agency].[Concept Scheme ID].[Concept Scheme Version].[Concept ID]
--* If the type is based on a text format of a component local representation, and;
--** The component id is required to be unique for all components within the scope of the structure which defines it (e.g. a dimension), the recommended name is [Component ID]
--** The component id is only required to be unique within the component list and which defines it (e.g. a metadata attribute), the recommend name is [Component List ID].[Parent Component ID]*.[Component ID]

--An attribute set is created for a report structure or a metadata attribute which contains child metadata attributes. This type is a complex type with a recommend name of [report structure identifier].[nested metadata attribute identifier].AttributeSet, where the metadata attribute section only applies to attribute sets created for metadata attributes and is assumed to consist of the full hierarchy of the metadata attribute's definition.

This complex type must consists of:
--Both the generic and the structure-specific data messages allow for incremental updating of data. This purpose is noted in the action for the data set, which is either inherited from the header of the data message or explicitly stated at the data set level.

--A dataset with an action of Append is assumed to be an incremental update. This means that one the information provided explicitly in the message should be altered. Any data attribute or observation value that is to be changed must be provided. However, the absence of an observation value or a data attribute at any level does not imply deletion; instead it is simply implied that the value is to remain unchanged. Therefore, it is valid and acceptable to send a data message with an action of Append which contains only a Series elements with attribute values. In this case, the values for the attributes will be updated. Note that it is not permissible to update data attributes using partial keys (outside of those associated with defined groups). In order to update an attribute, a full key must always be provided even if the message format does not require this.

--A dataset with an action of Delete is assumed to be an incremental deletion. The deletion is assumed to take place of the lowest level of detail provided in the message. For example, if a delete message is sent with only a data set element, the entire data set will be deleted. On the other hand, if that data set contains a data attribute, only that data attribute value will be deleted. This same dynamic continues through the data set hierarchy. A data set containing only a series with no data attributes or observations will result in that entire series (all observations and data attributes) being deleted. If the series contains data attributes, only the supplied data attributes for that series will be deleted. Finally, if a series contains observations, then only the specified observations will be deleted. If an entire observation is to be deleted (value and data attributes), only the observation dimension should be provided. If only the observation value or particular data attributes are to be deleted, then these should be specified for the observation. Note that a group can only be used to delete the data attributes associated with it. Although the format might not require it, a full key must be provided to delete a series or observation. It is not permissible to wild card a key in order to delete more than one series or observation. Finally, to delete a data attribute or observation value it is recommended that the value to be deleted be supplied; however, it is only required that any valid value be provided.
