Thanks voor the info Tom. I made the ticket: http://trac.osgeo.org/mapserver/ticket/4025, I was not sure in which component this applies to, so left it at the "MapServer C Library" .

At thispoint, filtering is only supported via UserStyle. Having said
this, please submit a trac ticket for the requirement. Not sure when/if
it would be addressed.
