* Notes: Does it make sense to refresh the subscription matches on a call to this method? I don't think so, the user theoretically had
* a set of entities in mind when the subscription was saved and the snapshot should remain just that - a snapshot of the entities at the
* time of the subscription save. The result of this policy is that if an entity is deleted, that deleted result will appear in the keyBag
* on every call to this method. To resolve this, the user can renew the subscription at which time the "match" snapshot will be refreshed.
*
* The WS needs to be authenticated (null publisher), however the notificationSubscriber is calling this method also. The
* notificationSubscriber will pass in the publisher and this method will work in unauthenticated mode.
