gml:AbstractGMLType

All complexContent GML elements are directly or indirectly derived from this abstract supertype 
	to establish a hierarchy of GML types that may be distinguished from other XML types by their ancestry. 
	Elements in this hierarchy may have an ID and are thus referenceable.

gml:id	[0..1]	xsd:ID	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.
