Only the BBOX spatial filter is supported but he BBOX can be used in
combinatiion with other filter types.
Example:
http://localhost/cgi-bin/mapserv-4.0?map=/home/httpd/html/prototypes/ec/msc/
config.map&version=1.0.0&service=WFS&request=GetFeature&typename=stn_info&
filter=<filter><AND><BBOX><PropertyName>Name</PropertyName><Box+srsName='EPSG:42304'>

The filter encoding support is in MapServer 4.1 cvs.

The BBOX parameter is mutually exclusive with FEATUREID and FILTER as
stated in the WFS specifications (see 13.7.3.1). So the BBOX is
supported as a GML element.

Subject: [Mapserver-users] WFS support
Hi all,
I do not seem to be able to filter my queries (WFS queries)
correctly. I read in the documentation that only BBOX filter
is supposed to work for WFS queries. Now does that mean that
only the BBOX filter will work among the spatial filters
(filters could be attribute filters or spatial filters) or
its BBOX filter alone without any other attribute or spatial filters.

In MapServer OGC:WFS (v4.0), BBOX works like this:

As for Filter, the forthcoming release of MapServer will support Filter
Encoding (is it already in CVS?), so you should be able to pull off queries

Now, I'm not sure whether spatial filtering will still be supported by the
