		<documentation>All geometry elements are derived directly or indirectly from this abstract supertype. A geometry element may 
		have an identifying attribute ("gml:id"), a name (attribute "name") and a description (attribute "description"). It may be associated 
		with a spatial reference system (attribute "srsName"). The following rules shall be adhered: - Every geometry type shall derive 
		from this abstract type. - Every geometry element (i.e. an element of a geometry type) shall be directly or indirectly in the 
		substitution group of _Geometry.</documentation>
