Stephen, Donal and others,

please see my comments interweaved below.

xsd:QName is a qualified XML name in respect that its local name part is of type xsd:NCName and allows for a namespace qualifier (like jsdl). It is thus a xsd:NCName extension (that doesn't allow for whitespaces either) with the optional ':' to form something like "jsdl:storageUnits".

I suppose xsd:QName is not needed for enumerations that we do not want to be extended by users (i.e. jsdlVersion). 
Since xsd:NMTOKEN allows for characters, digits, ".", ":" and "-", it forms IMHO a superclass (in terms of power, not formal inheritance) of xsd:QName.

Cheers,
Michel
