Xpointer and Axes question.

Is anyone using or played with XPointer XPath using Axes?  I am trying
to follow the examples in
http://metalab.unc.edu/xml/books/bible/updates/17.html and am not able
to make anything work which deals with "axis::node-test[predicate]"
location step.  Everytime I try to use "::" operation, nothing works.

Can anyone shed some light on this?  Do I need to install something to
make this work.


Environment:
IE5,
Win2k Server
IIS 5.0

Code snipit from the link shown above.

<x:include
href="familytree.xml#xpointer(id('p11')/descendant-or-self::PERSON)"/>
