[BA] The document allows the Access-Info Attribute in an Access-Challenge packet.  That doesn't seem compatible with "if any change is required you need to restart a session", because the value in an Access-Challenge could be different from that in an Access-Accept or Access-Reject.   Does inclusion in an Access-Challenge really make sense?
