  **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).

--**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).

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).

--**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).

--**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.

  **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)

--**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).

  == 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.

  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.
