Notes
-----
To include illustration of the flow resulting from step 5 in
section 4.2.2. § Server: Receiving SYN and responding with SYN-ACK

                   ..."The server MAY include data in the SYN-ACK packet
      if the response data is readily available.  Some applications may
      favor delaying the SYN-ACK, allowing the application to process
      the request in order to produce a response, but this is left up to
      the implementation."

It would be good to illustrate this alternative handshake in further updated document but this ack of illustration does not fault the protocol function, hence, this "technical" errata type is changed to "editorial" and status is set to held for document update.
