The problem seems related to BeautifulSoup NavigableString implementation which 
does not call PageElement `setup' method. By the way trying to modify the 
w3c.py code in order to do it after instantiating the NavigableString object 
was not effective.

It caused by BeautifulSoup 3.2.0, it use different structure with BeautifulSoup 
3.1.x which was used to create the demo.
