This is the tricky part - wish I could find my notes they have better
brain-dump.
It's OK to have the library as both front (config tool) and backend
(used by mesa) although:
 - special care on splitting and annotating the API is needed
 - handling this "extra" dependency would be fiddly for slower moving distros

What seems to be the problem with XML? The files are meant to be
read/written to $app.

The current setup handles GLX, DRI and Nine IIRC. One of my goals was
to split and structure this in a more obvious way.
