Certainly worth a look, but in my view using a database that does relational
data as well as XML has a big downside in terms of complexity. There's a lot
of functionality there that you don't need, and you can't ignore it - it
keeps popping up in all sorts of places, and it colours the whole flavour of
the product. Also, if you're in the position where you need to convince and
re-educate your developers to do everything the "pure XML" way, it's a good
idea to use technology that doesn't give them any choice.
