  Well changing the representation of the tree break both the API and ABI.
Seems the people from Xalan are going though this ATM and I have heard
some unhappy fellows about this.

  Breaking the representation means this would have to be a libxml3 effort.
I'm not saying this shouldn't be done, I actually presented this possibility
  http://veillard.com/Talks/2002Guadec/slide9-0.html

but it's a very significant work. I'm currently stuck with XML Schemas,
and it's gonna take some time ! That doesn't mean people interested in
evolution should not start seriously putting black on white what's needed
it just mean I can't focuse myself on this ATM.
