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.
