Hmm.. OK. Well, thank you all for clarifying that. I thought
(perhaps only hoped?) that the bar was lower for contrib than for core
as far as features go, but it seems that assumption is incorrect.
I'll look at starting a pgfoundry project soon.

A related question, however: Will the XML features being included in
8.3 support namespace prefix registration? If not, handling arbitrary
XML via XPath that includes unprefixed (default) namespaces (for me
that is the majority of the XML I deal with, and no, I can't change
that) will have exactly the same problems using the new mechanisms as
with the current xml2 contrib module. I ask because, based on the
design emails I've seen on -hackers, nothing surrounding explicit
support for said issue jumped out at me.

Thanks again.
