One solution to this is to define XPath 2.0 support in a separate  
document, as I suggested in an earlier message, in a way as orthogonal  
to other features as possible. This way XPath 2.0 support can be  
specified in a timeframe shorter than that of XForms 2.0. This also  
follows Mark's suggestion of doing smaller specs. XForms 2.0 could  
then normatively refer to that spec without duplicating the work.  
Again I don't know if or how our charter allows something like this,  
but it sounds appealing to me.

As for the functions in general, we could come up with dozens such  
functions for dozens of vertical industries. To me, these should not  
be part of the standard function library. I repeat myself, but there  
are so many limitations in XForms due to the use of XPath 1.0 that I  
think this is where we should concentrate our energy instead of  
patching things up, whatever the timeframe for the specs is.
