Some XML Questions

Well, to introduce myself, I'm not really a Be user, mailing list
posts to the contrary.

I'm interested, to start with, in writing a DTD for the XML format
that subversion uses. And I have a couple of questions.

1) Should the DTD cover the postfix delta format? I ask because it
isn't really possible, not without adding another root element outside
tree-delta?

2) (Random and pedantic) Does SVN_ERR_MALFORMED_XML represent
non-well-formed XML (as the name indicates) or invalid XML (as the
comment immediately preceding indicates)? It's unlikely that
subversion will actually validate the XML, since it's using expat,
which has no plans to become a validating parser.

3) Speaking of expat, since the subversion project began, expat has
undergone a number of radical changes. It is now autoconfiscated, and
libtoolized. It builds a shared library, and does other nice things.
Would people be interested in changing to the newer version? (Yeah, I
am volunteering for the work.)
