I've always wondered how the W3C looks issues of useability. I suspect
that if I had to teach XPath 2.0 to people, I would leave out most
things that were not in XPath 1.0 because I'd be scared to lose my
audience.

Getting XPath 1.0 expressions right is hard enough.. Personally, I
regard XPath expressions as atomic: they get me something out of a
document. There is no control flow in them, simple predicate tests
aside. With XPath 2.0, control flow will be scattered between the
languages built around XPath and the expressions themselves.
