  A //Constraint// has a choice of two ways of specifying value sub sets:
--1. As a set of keys that can be present in the DataSet (DataKeySet) or MetadataSet (MetadataKeySet). Each DataKey or MetadataKey specifies a number of ComponentValues each of which reference a //Component// (e.g. Dimension, TargetObject). Each ComponentValue is a value that may be present for a //Component// of a structure when contained in a DataSet or MetadataSet. The MetadataKeySet must also identify the MetadataTarget as there can be many of each of these in a MetadataStructureDefinition. For the DataKeySet the equivalent identification is not necessary as there is only one DimensionDescriptor and one AttributeDescriptor.

In addition, in (1) the association between //Component// and DataKeyValue or MetadataKeyValue is constrained to the components that comprise the key or identifier, whereas in (2) it can contain other component types (such as attributes). The value in ComponentValue.value and MemberValue.value must be consistent with the //Representation// declared for the //Component// in the DataStructureDefinition or MetadataStructureDefinition. Note that in all cases the “operator” on the value is deemed to be “equals”. Furthermore, it is possible in a MemberValue to specify that child values (e.g. child codes) are included in the constraint by means of the cascadeValues attribute.

  It is possible to define for the DataKeySet, DataKey, MetadataKeySet, MetadataKey, CubeRegion, MetadataTargetRegion, and MemberSelection whether the set is included (isIncluded = “true”) or excluded (isIncluded = ”false”) from the constraint definition. This attribute is useful if, for example, only a small sub-set of the possible values are not included in the set, then this smaller sub-set can be defined and excluded from the constraint. Note that if the child construct is “included: and the parent construct is “excluded” then the child construct is included in the list of constructs that are “excluded”.
