I don’t mind if you want to keep the second sentence, but it is a bit unclear to me as to what behaviour is out of scope. [Qin]:I think we can either remove the second sentence or replace it with " the backward compatibility aspects of EAG with respect to the AG are handled as described in the Backward Compatibility section of [RFC7308].
