[Zope] Documentation of attributes

Where can I find the list (and some kind of documentation !) of all standard attributes and methods (this(), aq-parent, ...). Hard to write any dtml method without that knowledge :-) By the way, I was testing the SimpleSiteMap example (http://www.zope.org/Members/djay/SimpleSiteMap) which recurse folder starting from aq_parent. Sometimes it works, sometimes not (empty result). Is this example out of date ?
