Attributes
| Name | Occ | Type | Description | Notes |
|---|---|---|---|---|
| srsName | [0..1] | xsd:anyURI | In 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:positiveInteger | The "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 |
