Wait. The "0.1" that Mapserver returns for the version is indeed the
version of the XML Schema. So in fact we should have a
Format.Schema.v0_1 and Format.Schema.v1_0 parser and mix this in for the
WFSDescribeFeatureType parser.

At least that is how it should be done. For now, your proposal does
definitely make sense, at least until we find some other use case where
we need to parse XML Schema. This can easily be refactored later without
changing the API.

Andreas.
