Just coming in from a tangent. I'm doing an XML database on top of the object 
database. But I use XPath instead of SQL, and so far I've not thought
much about supporting XPath queries into arbitrary XML-ified objects.
Note that this fulfills quite different requirements (no relations; I use
joins, but only internally), I just thought it would be cute to note the
orthogonality.
