Hi,

You can also try to add this to LAYER
wfs_extent

    Description: (Optional) Used for the layer's BoundingBox tag for cases where it is impossible (or very inefficient) for MapServer to probe the data source to figure its extents. The value for this metadata is "minx miny maxx maxy" separated by spaces, with the values in the layer's projection units. If wfs_extent is provided then it has priority and MapServer will NOT try to read the source file's extents.

And of course you should always be the boss and test with the basic hand written requests first before letting the GIS client to add for the complexity.
Something like these:

http://myserver.xx/cgi-bin/mapserv.exe?service=wfs&version=1.0.0&request=getCapabilities&map=path/to/the/wfs.map
http://myserver.xx/cgi-bin/mapserv.exe?service=wfs&version=1.0.0&request=DescribeFeatureType&typeName=mytest&map=path/to/the/wfs.map
http://myserver.xx/cgi-bin/mapserv.exe?service=wfs&version=1.0.0&request=GetFeature&typeName=mytest&maxFeatures=10&map=path/to/the/wfs.map
