      It is important to note what can and cannot be protected using
      the 'ClassSecurityInfo' interface. First, the security policy
      relies on *Acquisition* to aggregate access control information,
      so any class that needs to work in the security policy must have
      either 'Acquisition.Implicit' or 'Acquisition.Explicit' in its
      base class hierarchy.

         Here a document or reference to listing base class hierarchies 
         of zopes built-in classes might be wellcome.
