I've done an updated draft of the Custom XPath Functions feature, for 
possible inclusion in XForms 1.2.
The prior page had not been updated in a long time, but there were a lot 
of concerns about it because it was based on creating XPath variables. 
This version eliminates variables in favor of an internal instance. 
It comes out a lot cleaner this way, and it also enabled me to easily 
solve pretty much all of the related problems we were having.  It is, at 
least, a better "strawman" worth further discussion.

It would be very powerful to have this extension mechanism as a way to 
enable authors to create more powerful forms that work across 
implementations.

Cheers,
