I think you are already looking into this as part of a different thread.
It might have to be - as you noticed yourself - that you'll have to
extend the Schema class so that custom namespace prefices can be set.

Which I think is fine for the time being. It might be that this has to
change later on, but it might not be the case. I think it all depends on
what kind of simple type we are looking at ? E.g. xs:integer or a user
defined simple type (defined globally). For the latter I'd expect the
setReference() method to be used, for the former not.

As far as I remember, this is done through facets, and in your case the
enumeration facet in particular. Have a look at the EnumerationFactory
class to see how the reverse is done, i.e. how for a simple type
definition that has enumerations, these are accessed through the Facet
interface and looped over.
