hi,

i just saw the updated subscribe method
    
public org.apache.ws.pubsub.Subscription 
subscribe(
org.apache.ws.pubsub.NotificationConsumer notificationConsumer, 
org.apache.ws.pubsub.Filter[] filters, 
Calendar initialTerminationTime, 
java.net.URI deliveryMode, 
Object policy) {
    }

The problem is, that deliverMode is not just an URI, <delivery> is a 
bigger concept in WSE, which contains xs:any. For example in the implied 
deliveryMode which is PUSH (asynchron, unwrapped) there can be a 
<notifyTO> element which itself is a WSA EndpointReferenceType.

i think we should use the advantages of the WSE spec, which uses not so 
well defined but open concepts like delivery and filter. so it could look 
like

subscribe(notifconsumer, filter, termination, delivery, policy)

where filter is one interface, which can contain other filters like 
preconditions, selectors.....

Sam was talking about a plan in wsn tc, to also use such a broader concept 
of filter in WSN.

Delivery is also one interface, that contains information about 
wrapped/unwrapped for WSN or the deliverymode+notifyTO+XYZ for WSE.
