gml:AbstractGeometryType

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.

NameOccTypeDescriptionNotes
gml:id [0..1]xsd:IDfrom type gml:AbstractGMLType
srsName [0..1]xsd:anyURIIn general this reference points to a CRS instance of gml:CoordinateReferenceSystemType (see coordinateReferenceSystems.xsd). For well known references it is not required that the CRS description exists at the location the URI points to. 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 element like point, curve, etc. It is expected that this attribute will be specified at the direct position level only in rare cases.from group gml:SRSReferenceGroup
srsDimension [0..1]xsd:positiveIntegerThe "srsDimension" is the length of coordinate sequence (the number of entries in the list). This dimension is specified by the coordinate reference system. When the srsName attribute is omitted, this attribute shall be omitted. from group gml:SRSReferenceGroup
axisLabels [0..1]gml:NCNameListOrdered list of labels for all the axes of this CRS. The gml:axisAbbrev value should be used for these axis labels, after spaces and forbiddden characters are removed. When the srsName attribute is included, this attribute is optional. When the srsName attribute is omitted, this attribute shall also be omitted. from group gml:SRSInformationGroup
uomLabels [0..1]gml:NCNameListOrdered list of unit of measure (uom) labels for all the axes of this CRS. The value of the string in the gml:catalogSymbol should be used for this uom labels, after spaces and forbiddden characters are removed. When the axisLabels attribute is included, this attribute shall also be included. When the axisLabels attribute is omitted, this attribute shall also be omitted. from group gml:SRSInformationGroup
