It is invalid. The schema returned by the above requst doesn't validate 
against the XML schema of XML schema :-) from
https://www.w3.org/2009/XMLSchema/XMLSchema.xsd

Yes, using qgsextension:alias would validate XMLSchema.xsd as it has a 
provision for extra attributes in another namespaces.
That doesn't mean that Geomedia would be ready for it though. Depends on how 
it is coded...
