 Notes
 -----
 
-Bob must include the matching session ID in the reply Ephemeral Key Section for Alice to
-properly decrypt and bind the reply inbound session with the original outbound session.
-
 Multiple NSR messages may be sent in reply, each with unique ephemeral keys, depending on the size of the response.
 
 Alice and Bob are required to use new ephemeral keys for every NS and NSR message.
