Thanks for you quick reply and testing it :-)
1st: Ok, now I know that the SLD is working, but why not here?
2nd: Really? SVG isn't supported by MapServer? Then the use of it would be
quite senseless for me. Or will MapServer render lines/outlines of polygones
with PNGs or GIFs nicely? Because GeoServer doesn't (lots of gaps in the
lines etc.)!
Cheers and thanks again,
Christian.
