[Chameleon] WMS projection with alpha=90

[Schnider Markus]

Hi all

I am not sure if it's the right place or  will it be 'mapserver'
I have a umn mapserver wms server.
I would include a layer of this wms server. The projection of the layer has an 
alpha value of 90 (init=epsg:21781)
<21781> +proj=omerc +lat_0=46.95240555555556 +lonc=7.439583333333333 +alpha=90 
+k=1 +x_0=600000 +y_0=200000 +ellps=bessel +units=m +no_defs  no_defs <>
so I receive always an error message and the map cannot be shown.
I tried to change the projection in the mapfile (alpha=89 in the projection, 
nothing in the web part). The same behavior.
