IMHO the ItemTraverser should not lookup the view by itself, but
delegate to the 'view' traverser, somethind like:
def publishTraverse(self, request, name):
"""See zope.publisher.interfaces.IPublishTraverse"""
try:
return self.context[name]
except KeyError:
try:
return namespaceLookup('view', name, self.context,
request)
except TraversalError:
pass
raise NotFound(self.context, name, request)
