A geometry element may have an identifying attribute ("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>

 *                      <documentation>In general srsName points to a CRS instance of CoordinateReferenceSystemType (see coordinateReferenceSystems.xsd). For well known references it is not required that the CRS description exists at the location the URI points to (Note: These "WKCRS"-ids still have to be specified).  If no srsName attribute is given, the CRS must be specified as part of the larger context this geometry element is part of, e.g. a geometric aggregate.</documentation>
