     'IPermissionService' objects are used to implement
     permission-definition services. Because they implement services,
     they are expected to collaborate with services in other
     contexts. Client code doesn't sarch a context and call multiple
     services. Instead, client code will call the most specific
     service in a place and rely on the service to delegate to other
     services as necessary.

     The interface doesn't include methods for data
     management. Services may use external data and not allow
     management in Zope. Simularly, the data to be managed may vary
     with different implementations of a service.
