Nevermind slow and cumbersome engines, how is anyone supposed to teach
this stuff to people? It was hard enough to teach XPath 1.0 to
non-programmers, but this almost looks like a programming language now.

I find it quite unbelievable how badly the W3C is managing the xquery,
xslt and xpath evolution. If someone handed you a piece of code that
separates its concerns so badly, you would send them back to refactor

Instead of getting specifications that complement one another, we get
redundantly specified specs that are seriously complicated.. who's
supposed to keep an overview over all this?

And the backwards incompatibility of XPath 2.0 is an absolute
nightmare.. it doesn't exactly affect 'marginal' paths, it's going to
break a few of mine at least.

Way to go! :)

You've got my vote! I'm actually not too dissatisfied with XPath 1.0, it
meets my requirements, barring the absence of transitive closure..
