I am truly sorry I've run out of time for active participation in this thread...

I agree with most of your post Jeni.  The one thing that would be nice to see introduced into XPath is some sort of shortcutting in certain operators (either the boolean operators, or with an introduced ternary operator).  XPath 2.0's if expressions provide this.  If course, short-cutting is really much nicer and safer in a side-effect-free language, so XPath 2.0 manages to chuck this advantage as well.
