There is no "the set of functions" associated with any particular  
datatype, which I think is what's underlying the other Lars's point.

I think we could usefully cut this down to what XPath 1.0 had. We've  
used that function set as predicates in tolog, and it's worked very  
well for us. It also worked very well for XPath/XSLT.

Yes. So we have to balance compatibility of implementations against  
complexity of implementations. If we lean too far over toward  
complexity we get no implementations at all, and so theoretical  
compatibility is no gain. :)
