gml:_CRS

Abstract coordinate reference system, usually defined by a coordinate system and a datum. This abstract complexType shall not be used, extended, or restricted, in an Application Schema, to define a concrete subtype with a meaning equivalent to a concrete subtype specified in this document. 

Element information

Content

• Sequence [1..1]
  from type gml:AbstractReferenceSystemBaseType
  gml:metaDataProperty [0..*]    Contains or refers to a metadata package that contains metadata properties.
