[ZPT] Path expression

[Paul Everitt]

In addition to the TALES spec wiki page, please remember that the Zope 
Book has excellent documentation on ZPT:

   http://www.zope.org/Documentation/ZopeBook/ZPT.stx
   http://www.zope.org/Documentation/ZopeBook/AdvZPT.stx
   http://www.zope.org/Documentation/ZopeBook/AppendixC.stx

Even better, the docs are now using ChrisM's BackTalk system.  This 
makes it *really* easy to find a spot and make a comment.  Chris and I 
are getting 75% of the comments handled (we get emailed) within the 
first 24 hours.

If you have a question on something that you think should be documented, 
or have some handy tips, please take 5 minutes and throw something in 
there.  We'll take care of the rest.
