invalide extension in the wms capabilit y file

Tue Feb 7 19:59:14 PST 2006

Rainer, depends on your use i guess.

Have a read through all the options at,

http://mapserver.gis.umn.edu/docs/howto/wms_server/?searchterm=wms

Most of the optional paramters are for CITE compliance or other 
features (such as WMS-Time and WFS).

So long as your capabilities are reporting the correct online_resource 
url and a correct BBOX, most clients should function without any 
problems.
