It's an important feature.  Right now I'm trying to make my way to
the just-related last-call formal spec, and see if that gives me any
guidance.  (I need to have a general understanding of the formal spec
anyway.)

If we want access to the PSVI then Qexo needs to access the data
structures that Xerces2-J uses to represent types.  So we're tied
to Xerces anyway.  I think using XNI will be more efficient, so
I think we should use it.
