Thanks for this input :)

To begin, PostGIS 'only' handle geometry part of GML. and not the  
whole GML document.

So most of the changes here seems not really PostGIS care but rather  
the WFS engine who deal
with it (GeoServer, TinyOWS...)

For now ST_GeomFromGML is already able to handle GML 3.2 namespace if  
present
in the GML geometry fragment.

Humm what do you mean there ?
For information, we handle SFS GeometryCollection as GML MultiGeometry  
for now


Did you seen any geometry change in GML schema beetween 3.1.1 and  
3.2.1 ?
