4.1.1 Establish the Sequences
The RMS emits a new sequence identifier and sends it to the RMD on a CreateSequence message that includes an Offer element (lines 15-17). The CreateSequence message indicates the RMS is anonymous (an empty projection of the [reply endpoint] addressing property implies an anonymous reply endpoint, as specified in [WSASB]) and carries an anonymous address in the AcksTo Endpoint (lines 12-14).

The RMD responds by emitting a new sequence identifier and sending it to the RMS on a CreateSequenceResponse message (line 11). The CreateSequenceResponse message indicates acceptance of the offered sequence (lines 12-16).
