Where do you need to look inside IRIs, in going between the PS and XML?
I would consider it incorrect to change the IRIs during this conversion,
even it was just making IRIs absolute, etc, so I'd think they should be
considered entirely opaque during this translation.

In going from XML to native language, you'll need to do conversion to
absolute URIs, but not in dealing with the PS..... (I think).

(And yes, I would expect every modern language to have a URI parsing
toolkit.  Python certainly does, and I think SWI Prolog does, too.)
