Just because RNG gracefully leaves the infoset alone doesn't mean
that you must never want to access type information found in
RNG schemas when processing instance documents with XPath.
If XPath 2.0 had taken a modular approach, it could have supported
schema-defined-type aware processing for arbitrary schema languages.

Cheers,
