SLD has no effect

[Bjoern Platzen]

Hi List,

in the past two days I read a lot about not-working SLD's, but none of the
tipps I found could solve the problem for me.

As a first step I tried to change the symbol of a point-layer via SLD, but
even this did not work. It just has no effect if I specify an SLD through
the link. The map is always drawn in the way, that is specified in the
mapfile.
The mapserver supports WMS-Server and SLD, the SLD is accessible via HTTP,
the image, that should be used as the symbol is accessible as well.

So here's the Mapfile:

  END

  END

The Symbol-definition:

  TYPE PIXMAP
  Image 'images/chio.png'
  Transparent 63
END

... and the SLD:

Last but not least, here is the Link:

As SLD seems to work with umn-mapserver for a lot of people out there, I
think, that I have messed up something, but I just don't see what...

Any help is highly appreciated.

Thanks in advance,
