Section 126.96.36.199,p.35 says:
The sending node defines the Heartbeat Data field contents. It may include a Heartbeat Sequence Number and/or time stamp, or other implementation specific details. The receiver of a Heartbeat message does not process this field as it is only of significance to the sender. The receiver echoes the content of the Heartbeat Data in a BEAT ACK message.
It should say:
The receiver of a Heartbeat message echoes the content of the Heartbeat Data field contained therein without further processing in the Heartbeat Data field of the Heartbeat Ack message.
Apparently, the quoted text has been copied from 188.8.131.52 without
performing the appropriate rewording to accommodate the context
of 184.108.40.206 (BEAT ACK message).
