[mapserver-users] invalid schema location?

Hi,

I believe that the whole OUTPUTFORMAT is unnecessary with DescribeFeatureType and if it is not needed then why to keep it?   I am not a xml specialist, but I feel that the following request is returning a valid WFS 1.0.0 schema:
http://localhost/cgi-bin/mapserv.exe?map=d:\data\maps\wfs_test.map&service=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=wfstest

and this one sends back a valid WFS 1.1.0 schema:
http://localhost/cgi-bin/mapserv.exe?map=d:\data\maps\wfs_test.map&service=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&TYPENAME=wfstest

Wouldn't it work correctly if the first request is used as a schema location always if GetFeature is asked with gml2 as outputformat, and the latter one with gml3 output?
