The gml:AbstractFeatureCollectionType is deprecated in GML 3.2.
GML 3.2 spec chapter 9.9.1: "A GML feature collection is any GML feature with a property element in its content model whose content model is derived by extension from gml:AbstractFeatureMemberType".
- Make AbstractMeteorologicalObjectCollectionType extend gml:AbstractFeatureType
- Add new type MeteorologicalObjectMemberType including or referring to any AbstractMeteorologicalObject
- Add a property "member" of type MeteorologicalObjectMemberType to AbstractMeteorologicalObjectCollection with 0..n multiplicity
Note: this means that staring from version 2011/03/15 WOML collections may only include WOML features, and no longer any GML features.
