NotificationResponse for every Notify request?

Hi,

I have implemented a service that consumes notifications (i.e. NotificationConsumer capability).

But for each <Notify> message I see a <NotifyResponse>:

<soapenv:Envelope
    xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope" xmlns:wsa="http://www.w3.org/2005/08/addressing">
    <soapenv:Header>
        <wsa:To>http://www.w3.org/2005/08/addressing/anonymous</wsa:To>
        <wsa:ReplyTo>
            <wsa:Address>http://www.w3.org/2005/08/addressing/none</wsa:Address>
        </wsa:ReplyTo>
        <wsa:MessageID>urn:uuid:9CAC3C71040F9D76F4123824223414018</wsa:MessageID>
        <wsa:Action>http://docs.oasis-open.org/wsn/bw-2/NotificationConsumer/NotifyRequest</wsa:Action>
        <wsa:RelatesTo wsa:RelationshipType="http://www.w3.org/2005/08/addressing/reply">uuid:138ee423-37af-c545-66bd-6f7cdaaece6a</wsa:RelatesTo>
    </soapenv:Header>
    <soapenv:Body>
        <wsnt:NotifyResponse
            xmlns:tns="http://axis2.platform.core.muse.apache.org" xmlns:wsnt="http://docs.oasis-open.org/wsn/b-2"/>
    </soapenv:Body>
</soapenv:Envelope>

In WsnConstants.java I found:
// HACK: This is not defined by the standard, but we need something to
//       send back to blocking clients
//
public static final QName NOTIFY_RESPONSE_QNAME =
        new QName(NAMESPACE_URI, "NotifyResponse", PREFIX);

1. Can I disable the submission of these replies in any way?

2. Something else, didn't spot this in WS-BN spec: is there any way to enable assured delivery for notifications?  We are planning to use then for fault-tolerant experiments in our lab.  Suppose WS-RM could come in here?  Any suggestions?

3. I have a service that in its initializeCompleted() starts a thread to send notifications every 10 seconds, but after a while - when the client program (main) stops - messages stop flowing too.  How can I make sure the service will persist in sending messages in time?  Log doesn't give any more info.  Subscription was made with null as time-out, so I should go on forever?
