H.323's "keepAlive" mechanism

According to the text in section of H.323v4 (11/2000), as a response
to a RRQ, a GK may respond with an RCF containing a timeToLive that is equal to
or less than the timeToLive from the RRQ. This raises two questions:

1) Why isn't it allowed for a GK to respond with a greater value, or any value for
   that matter?
2) If the EP does not specify a timeToLive, should this be treated as a value
   of "0" and does this make it impossible for a GK to impose any timeToLive
