you have to declare an *allowed_interface* or an *allowed_attribute* 
attribute inside the page directive, too.

look at the absolute for example:

 <browser:page
     for="*"
     name="absolute_url"
     class=".AbsoluteURL"
     permission="zope.Public"
     allowed_interface=".interfaces.IAbsoluteURL"
     />

\src\zope\app\traversing\browser\configure.zcml
\src\zope\app\traversing\browser\interfaces.py
\src\zope\app\traversing\browser\absoluteurl.py
