Sounds reasonable, sure I'd be happy to help.

I took a brief look through this stuff a couple of weeks back, and our XML parsing code is fairly hairy to update.

Large chunks of our code for parsing config type stuff seem to be passing their work through some kind of XSLT layer, 
which confuses me.

Various things in xmloff/ implement both XFastParser and XParser helper code, and it's not obvious what subclasses need 
to implement to tie into the helper routines, etc, etc.

I think Azorpid will have his work cut out :-)
