Read that; interesting.  Of course, what counts as "navigating markup"
partly depends on the accident of what happens to be available in
XPath, which is a very different story between 1.0 and 2.0.  So I don't
think there's any theoretical distinction here, just a practical one,
generally consistent with the idea that my code is just data consumed
by your interpreter.
