Section 3.3.2.6,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.
Notes:
Apparently, the quoted text has been copied from 3.3.2.5 without
performing the appropriate rewording to accommodate the context
of 3.3.2.6 (BEAT ACK message).
