Yes, but only in the special case of ++namespace++ traversal. This is  
what I said in the above paragraph already. zope.publisher itself  
doesn't depend on zope.traversing and the default publication  
implementation in zope.app.publication uses zope.traversing only for + 
+namespace++ names (see usage of zope.traversing.namespace.nsParse in  
zope 
.app.publication.publicationtraverse.PublicationTraverse.traverseName).
