Concrete element in the _MetaData substitution group, which permits any well-formed XML content. Intended to act as a container for metadata defined in external schemas, for which it is not possible to add the concrete components to the GML _MetaData substitution group directly. Deprecated with GML version 3.1.0.
Database handle for the object. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs. An external identifier for the object in the form of a URI may be constructed using standard XML and XPointer methods. This is done by concatenating the URI for the document, a fragment separator, and the value of the id attribute.
