Only DiscussionItemContainer has a __bobo_traverse__ method.

Five was changed a while ago to make sure views don't mask attributes:
http://codespeak.net/pipermail/z3-five/2006q1/001186.html

Skin methods are attributes of the portal root (see __getattr__ of 
SkinnableObjectManager), but not of sub folders. Views are looked up 
after attributes but before acquired attributes.
