[wms-dev] WMS servers supporting user styles

[Yewondwossen Assefa]

Richard,

My general feeling is that the SLD should always be used in a library
mode (at least thet is the way I always understood it) with LAYERS
parameters being the one controlloing the returned layers. But since It
is defined in the specs to have dual way of functionning, you could add
this as an enhacement bug and It will be adresses for future releases of
Mapserver.

Best Regards,
