Section 4.9.5 says:

   Holdtime
        The amount of time a receiver must keep the Join/Prune state
        alive, in seconds.  If the Holdtime is set to '0xffff', the
        receiver of this message should hold the state until canceled by
        the appropriate canceling Join/Prune message, or timed out
        according to local policy.  This may be used with dial-on-demand
        links, to avoid keeping the link up with periodic Join/Prune
        messages.

        Note that the HoldTime must be larger than the
        J/P_Override_Interval(I).

It should say:
