No, they don't. "publication namespaces" are just valid traversal steps 
(adapters). TALES uses traversal the same way the publisher does. The TALES 
namespaces are what they are: Namespaces (iow, adapters) for TALES 
expressions.

While this is not an implemented distinction, it is probably is a logical one.
