For conditions, see OGC Software Notice http://www.opengeospatial.org/about/?page=ipr An abstract feature provides a set of common properties, including id, metaDataProperty, name and description inherited from AbstractGMLType, plus boundedBy. A concrete feature type must derive from this type and specify additional properties in an application schema. A feature must possess an identifying attribute ('id' - 'fid' has been deprecated). deprecated deprecated in GML version 3.1 Bounding shape. Envelope that includes also a temporal extent. Container for a feature - follow gml:AssociationType pattern. Container for features - follow gml:ArrayAssociationType pattern. A feature collection contains zero or more features. Concrete generic feature collection. Makes boundedBy mandatory deprecated deprecated in GML version 3.1 Deprecated in GML 3.1.0 Convenience property for generalised location.
