annotation	documentation These four attributes represent the standard IVOA referencing system: internal (within the document) referencing through "id" and "idref", external referencing through Xlink, using only "type=simple" and "href". documentation The attributes ID_type and IDREF_type allow the author to list attributes of type ID, respectively IDREF, enabling readers to identify these attributes without having to refer to the schema. This is important in cases where documents are concatenated (e.g., in registries), raising the potential for non-unique IDs. The value of these attributes is a string of comma-separated attribute names.
