<complexType name="AbstractGeometryType" abstract="true">
<annotation>
<documentation>All geometry elements are derived directly or indirectly from this abstract supertype. A geometry element may have an identifying attribute (gml:id), one or more names (elements identifier and name) and a description (elements description and descriptionReference) . It may be associated with a spatial reference system (attribute group gml:SRSReferenceGroup).
The following rules shall be adhered to:
- 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 AbstractGeometry.</documentation>
