No, 

Mapping of any XML document by XSD is on TODO list yet.
Now we can eat only own XML dump.

I afraid I do not see deeply your idea yet.

What other searches except attributes, you may want to do on such data?

Well, I can guess just analyze data.
And XML here was only container to bring data to DB.
Right?


---------
about cyclical graphs

Here important just to be able recognize a circle and stop move by it,
instead keep move down/up?

If yes, then I think this is very easy.

But will be good to hear examples from you on this. And more detailed
explains.
