David:
How about rephrasing the sentence on lines 1738-1739 as:
"For a reliably delivered message, TimeToLive MUST be greater than
(Timestamp + Retries * RetryInterval)."
I also agree with Dan that ExpirationTime would be a better name than
TimeToLive. However, that will trigger other requisite descriptive
changes because we currently have an errorCode named
TimeToLiveExpired.
