[mapserver-users] QGIS / Mapserver WFS filter (bbox/envelope) interoperability issue

Hi Andreas,
	
this is quite unfortunate MapServer doesn't support gml:Envelope as a geometry in the 
"Intersects" request, whereas we support it inside a <BBOX> filter.
The optimistic in me says that shouldn't be too hard to fix.

The supported geometries inside "intersects" are at:
https://github.com/mapserver/mapserver/blob/master/mapogcfilter.cpp#L1015

It doesn't look however that gml:Box would be legal in GML 3.2 (so with WFS 1.1 or 2.0) as it 
is a legacy from GML 2 or perhaps even older. MapServer doesn't care much about GML 
versions and compliance to schema on input side, but other servers might reject a 
fes:Intersects with a gml:Box
