107 107  It is possible to define for the DataKeySet, DataKey, CubeRegion, MetadataTargetRegion and MemberSelection whether the set is included (isIncluded = "true", default) 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”.
