This gives a flexible mechanism by which the actual objects need not be defined in concrete terms in the model but are defined dynamically by the IdentifiableObjectSelection. In this way, the MetadataStructureDefinition can be used to define any set of MetadataAttributes regardless of the objects to which they can be attached.

Note that if the [[Representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is non-enumerated then the association is to the ExtendedFacet (which allows for XHTML as a FacetValueType). If the [[Representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is enumerated, then is must use a [[Codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]].
