SubscriptionPolicy support?

[Vinh Nguyen (vinguye2)]

Hi,
 
I noticed that in WS-BaseNotification-1_3.xsd, the Subscribe input takes
in 4 parameters: ConsumerReference, Filter, Date, and
SubscriptionPolicy.
 
But, the NotificatonProducerClient.subscribe() method doesn't have the
SubscriptionPolicy parameter.  Any reason why this object is left out?
 
Aloha,
