         *  We don't use c++ dynamic cast here because we
         *  are refusing to impose any restrictions on
         *  facet representation types, so in particular
         *  they will likely be of unrelated type.
         *
         *  Instead rely on the interface pointer to access
         *  information about the runtime type associated
         *  with a stored fat-object-pointer representation.
