xml support

[Ruan Strydom]

I am trying to make a xml support plugin which consists of (for now):
1) tree view (first phase almost done)
2) formatters (done)
3) validator (almost done)
4) problem reporter (must still do)

This is what the xsd tree looks like and want to know if its ok, perhaps 
someone can give me pointers on improving it, make it more use-full?

ps: The idea is that you can add elements to the tree, although it would 
probably come later.
