I find it a bit amusing that the standard says GetFeatureInfo must not
copy the VERSION parameter from the GetMap request, when VERSION is a
required parameter in the GetFeatureInfo request. I guess you could
make a GetFeatureInfo request with another WMS version, but would it
really make any sense to set up a WMS 1.1.1 client that creates WMS
1.3.0 GetFeatureInfo requests?

Also, for the GetFeatureInfo request, there's only one accepted value
for the EXCEPTIONS parameter, so clearly this parameter cannot be
copied from the GetMap request.
