Actually I don't need this, I'd just like to generate:

      Datatype qnameDatatype = ...;
      QName abc = (QName)qnameDatatype.createValue(literal, context);

where 'literal' is some value read from an XML stream.

I assume that's because I'm ok with the generated code depending on the 
datatype library.

For the purposes of my generator all that's missing for read access is a 
getValueType() method.

I agree that when it comes to transforming to literals the issue is 
somewhat more complex than I indicated. But isn't what's needed 
basically a registerNamespace(String uri, String prefix) method in the 
context?
