Firstly, XPath 1.0 is still the current version of the language. XPath 2.0
is only work in progress.

Secondly, W3C doesn't generally modify or withdraw Recommendations once they
are published (though they are sometimes updated to correct errors). It's
important that there should be a good level of trust that when you refer to
a Recommendation, the document you read on the web today should be the same
as the one I will read tomorrow. Admittedly, this trust wouldn't disappear
if a forwards reference were added to a subsequent version. But it would
raise awkward questions, like should the normative references at the end of
the XPath spec be updated to refer to later versions of other
specifications?

The best way to find current versions of all W3C specifications is to start
at http://www.w3.org/TR/ which gives all the specs and their current status.
