Hi Marco,

thank you for clarifying, you are absolutely right and it seems that it was
dropped after 1.0, my issue is related to "GetStyles" request, (please
notice the trailing "s"), I used this documentation
http://portal.opengeospatial.org/files/?artifact_id=1188)  :

13.1. GetStyles
The GetStyles operation is used to retrieve user-defined styles from a WMS.
parameters of the HTTP-GET method are defined as follows:
Parameter Required Description VERSION Required
 Version as required by OGC interfaces.
REQUEST Required Value must be “GetStyles”.
LAYERS Required Comma-separated list of named layers for which to retrieve
SLDVER Optional The SLD version requested for the SLD document. The default
to return the highest version supported by the server. If a version
is requested that the server does not support, then the next lower
supported version is supported by the server is returned, or the
server’s lowest supported version. This is similar to WMS version

If I understand this correctly, we should split GetStyle and GetStyles
calls and support the second one only if SLDVER is set and  SLDVER=1.0.0,
raise an exception if not match.

GetStyles should then accept the following parameters:

LAYERS=comma separated list of TypeNames
SLDVER=1.0.0 (this seems the only version that supports GetStyles)

BTW: does anybody know what method took the place of GetStyles after it was
