Thanks, I'll do, but first I need to know why the QGIS Server code is as
ist is, I can't believe it's just an error.

I'm still confused: I know that GetStyles is an OGC method and GetStyle
isn't, but QGIS apparently doesn't, see line 705 in qgis_map_serv.cpp :

request.compare( "GetStyles", Qt::CaseInsensitive ) == 0 ||
request.compare( "GetStyle", Qt::CaseInsensitive )

so, it seems like QGIS server will serve both GetStyle and GetStyles
exactly the same.

Second point (that was my original problem) is why the STYLE parameter that
is both unused and out of the specifications is mandatory, unless I'm
completely missing the point, I dont' think it is a good idea to keep it.

So, please explain me why QGIS Server behaves like that, and if  there is
not a good reason, just tell me and I can provide a patch to remove that
