Thanks for replying Bart and Tom.
I tried your mapfile Bart and I still got the same junk error...so then I wondered if it
is a mapserver version issue of mine, so I got the lastest version and voila my own
mapfile works. I was using a build from October...what had changed since then that
affected this WFS call???
Anyway problem solved, and thanks guys for helping me.
