    <thetext>WS-Eventing section 3.1 specifies wse:Identifier: &quot;In some cases, it is convenient for all EPRs issued by a single event source to address a single Web service and use a reference parameter to distinguish among the active subscriptions. For convenience in this common situation, this specification defines a global element, wse:Identifier of type xs:anyURI, that MAY be used as a distinguishing reference parameter if desired by the event source.&quot;

Three issues may be caused by removing &lt;wse:SubscriptionManager&gt; in &lt;wse:SubscriptionEnd&gt; per Issue (http://www.w3.org/Bugs/Public/show_bug.cgi?id=6397):
1)       It  may force a subscriber to create its own id and correlate it with the wse:Identifier returned by the event source. 
2)       It eliminates a common case where wse:Identifier alone can be used to correlate SubscriptionEnd and subscriptions;
3)       It creates backward compatibility issue when implementations use wse:Identifier in SubscribeEnd message;

Proposal:
Instead of removing &lt;wse:SubscriptionManager&gt; from SubscriptionEnd, move it to the WS-Addressing [source] EPR of SubscriptionEnd message.
This 1) preserves the wse:Identifier and 2) is consistent with the modeling of SubscriptionManager. The new message template looks like this:
&lt;s:Envelope &gt; 
  &lt;s:Header &gt;
    &lt;wsa:From&gt;
     &lt;wse:SubscriptionManager&gt;
        endpoint-reference
      &lt;/wse:SubscriptionManager&gt;
    &lt;/wsa:From&gt;?
    &lt;wsa:Action&gt;
      http://schemas.xmlsoap.org/ws/2004/08/eventing/SubscriptionEnd
    &lt;/wsa:Action&gt; 
    
  &lt;/s:Header&gt;
  &lt;s:Body &gt;
    &lt;wse:SubscriptionEnd &gt;
      &lt;wse:Status&gt;
        [
    http://schemas.xmlsoap.org/ws/2004/08/eventing/DeliveryFailure | 
    http://schemas.xmlsoap.org/ws/2004/08/eventing/SourceShuttingDown |
    http://schemas.xmlsoap.org/ws/2004/08/eventing/SourceCancelling
        ]
      &lt;/wse:Status&gt;
      &lt;wse:Reason xml:lang=&quot;language identifier&quot; &gt;xs:string&lt;/wse:Reason&gt; ?
      
    &lt;/wse:SubscriptionEnd&gt;
    
  &lt;/s:Body&gt;
&lt;/s:Envelope&gt;</thetext>

    <thetext>All but 1 of wg on 2009-01-15 agreed to not open this issue as it was thought to be a re-opening of 6397 without enough new information to support reconsideration.
