<documentation>This derives from gml:DynamicFeatureType, as all AIXM features are expected to have temporal properties modeled using the Timeslice model. While the GML specification does not mandate that dynamic features derive from gml:DynamicFeatureType, many GML-aware applications may only detect a dynamic feature by this type hierarchy. Note that all temporal properties of gml:DynamicFeatureType are removed during this restriction, because they will be added for each AIXM feature specifically, based on the TimeSlice model</documentation>
