Implementing XML-versioning?

Hello,

I'm writing my master thesis on versioning of XML documents, especially
OpenOffice-files.
Up to now, I tested several diff algorithms and I'm trying to figure out,
whether it is possible to implement one of them into subversion.
The problems I see are:
- the delta of the xml-diff has another format (but it's still an xml-file)
- the xml-diff can't handle three-way merges
- up to now, you can't check whether two deltas commutate (however, this
should be solveable)

My main questions are:
- is it possible to change subversions' diff-algorithm at all? Jim Blandy et
al. mention a client side diff-plugin support which should be implemented
after 1.0. Where can I find more information about it?
- where would be the best point to start implementation?

I would be thankful if anyone could give me some hints concerning above
questions.
