XPath doesn’t really help with extracting the data, only with finding it.
I’m sure Julian Reschke would be able to write some xslt for this :-)

Right.  The important thing is that it can reference another document, which can then independently move forward.  But that would need to *export* its registry content (probably via XML…) in a common format.
Lots of tooling needed.

Absolutely.  But maybe we can design it in a simple enough way so we can use it, too.
