Hi Marco,

Firstly I would like to update WMS 1.3.0 GetCapabilities for properly 
declare the request GetLegendGraphic. This request is defined in 'Styled 
Layer Descriptor profile of the Web Map Service Implementation 
Specification'. One of my customer needs it to add his QGIS-Server WMS 
layers in a GeOrchestra application.

Then I think it will be useful to have GetStyles in WMS 1.3.0 and not 
only in WMS 1.1.1. GetStyles is the motivation behind 
getSchemaExtension. The Open Geospatial Consortium gives a way to 
declare extended request in WMS 1.3.0 and MapServer use it to add this 

Finally I think GetCapabilities is the right place to declare extended 
request like GetLegendGraphic or GetStyles. GetPrint has probably to be 
simplified in GetCapabilities. The extended schema is not for add all 
the project settings in GetCapabilities but to decare request for 
clients and other interoperable applications like GeoServer, GeoSource, 
GeOrchestra, etc.
It's also a way to declare QGIS-Server extended request like : 
GetProjectSettings, GetContext, etc.
