  **//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.

  **//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. The same rules for derivation as the base data set type apply to this specialized data set.
