In WS-Eventing where the client (event sink) does not know when the events may be delivered it is useful to generate an EmptyFilter fault that indicates to the client that it may never receive a notification for the subscription.  However, the situation is different in WS-Enumeration, where the client is expected to pull the enumerated elements. If the filter supplied with the enumeration context resolves to zero elements, then the PullResponse will contain an wsen:EndOfSeqeunce element that indicates that no enumeration elements are available for the enumeration context that had been set up. This provides the state of the enumeration to the client and hence there is no need for an EmptyFilter fault.

Thanks.
