NATs can use a idle timer for their bindings. For a given binding the idle 
timer gives the time until the resource is freed again without any data 
traffic.

Policy Reserve Rule (PRR) reserves just an external IP address and port 
number at NAT, but does not necessarily allocated any NAT binding. So 
MaxIdleTime is not required in PRR, since in anyway no data can pass the 
NAT bindings (sessions are not generated at all).
