4Suite supports XML namespaces, but you have to add them when you create the
Context object. I found this very confusing at first, especially since
documents which have a default namespace can't use a "default" prefix (a null
string). Prefixes used to define namespaces in the original document do not
have to match prefixes in the XPath context (but the namespace strings, the
URLs, do). If all of this is just adding to the confusion, I'll try to post
my XPath for ZPT tonight, which uses 4Suite and namespaces. I've tested it
with ParsedXML, but not with ParsedXML + Namespaces yet due to a problem with
my ParsedXML install--I can't create new instances. I'll try to test in
anyway on the train home and let you know the results.

Um, I don't know. It should to the extent that ParsedXML and 4Suite's
XPath implementation support namespaces, but I'm not much of a namespce
guru so perhaps there are special UI or API requirements you have?
We could see about adding something.

I'll just say you're for now the Zope-XML XPath namespace guru. I myself at
least will depend on your zen. :)

Okay, sounds good. Looking forward to seeing it!
