<complexType name="RegisteredSpecificationPropertyType">
  <annotation>
    <documentation>Property type containing one plain diggs:Specification, as held by a registry entry. Deliberately carries NO gml:AssociationAttributeGroup, for the same reason diggs:SpecificationRegistryEntryPropertyType does not: a registry holds its Specifications by value. If this permitted xlink:href, a registry could register a standard it does not itself contain, and the canonical copy would stop being canonical. Distinct from diggs:SpecificationPropertyType (core/Common.xsd), which DOES carry the association group - that is what lets an instance document cite a registry entry by reference in the first place.</documentation>
