What may not be clear here is that JAXP is not itself a parser -- it's a
parser abstraction layer.  If JAXP is explicitly disallowing some features
of XML, that means that no parser can implement those features as long as
that parser is accessed through the standard, parser-independent API.

This isn't just a non-conformant parser -- this is a platform's standard
API insisting that it absolutely will not work with a conformant parser
(if one were to be implemented).

If they allowed everything, even if their default implementation didn't
handle it properly, there's at least room for alternate implementations to
handle everything properly.  (On the other hand, then you have differences
across implementations, which is what JAXP is trying to prevent, so you
might as well not even bother with JAXP, and just write
implementation-specific code.)
