--***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. The group can consist of either a subset of the dimensions defined by the data structure definition, or an association to an attachment constraint, which in turn defines key sets to which attributes can be attached. In the case that the group is based on an attachment constraint, only the identification of group is provided. It is expected that a system which is processing this will relate that identifier to the key sets defined in the constraint and apply the values provided for the attributes appropriately. Data structure definition schemas will drive types based on this for each group defined in the data structure definition. Both the dimension values which make up the key (if applicable) and the attribute values associated with the group will be represented with XML attributes. This is specified in the content model with the declaration of anyAttributes in the "local" namespace. The derived group 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). The dimension XML attributes will be required while the attribute XML attributes will be optional. To allow for generic processing, it is required that the only unqualified XML attributes in the derived group type be for the group dimensions and data or metadata 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 dimension or attribute.

For example, a repeated value, a text value in multiple languages, or a value with structured text (XHTML) cannot be expressed as an XML attribute. This type is meant to be restricted based on the component to restrict the cardinality and type of its Value element to conform to the component definition. The type of the value element should be restricted to common:SimpleValueType, common:TextValueType, or common:StructuredValueType. In addition, the id attribute should be restricted to be a fixed value with the component identifier. This restricted type based on the component can then be used on Comp elements by using the xsi:type to state the component being expressed and refine the contents of the element to the values allowed by the component.

  **MetadataSetType:** MetadataSetType describes the structure for a metadata set, which contains a collection of reported metadata against a set of targets. The targets should conform to the restrictions described by the metadata provision or the metadataflow. Note that this is maintainable, and as such must specify in agency. In this case, the agency is the metadata provider. If a metadata provision agreement is referenced, it is assumed that the metadata provider described in the provision will be the same as the agency for this set.
