I'm mostly persuaded, mostly because XPath 2.0 will be accessible 
through the XSLT 2.0 component anyway. My only reservation is that if we 
choose XPath 1.0 now, but want 2.0 later, we will have to handle all the 
interoperability issues then. If we went for 2.0 (and no choice) now 
then we wouldn't have to worry about XPath version interoperability for 
a long long time.

Cheers,
