			<documentation>The basic feature model is given by the gml:AbstractFeatureType.
The content model for gml:AbstractFeatureType adds two specific properties suitable for geographic features to the content model defined in gml:AbstractGMLType. 
The value of the gml:boundedBy property describes an envelope that encloses the entire feature instance, and is primarily useful for supporting rapid searching for features that occur in a particular location. 
The value of the gml:location property describes the extent, position or relative location of the feature.</documentation>
