versioning question

      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.
