were deleted.<p>

subscriptions of the affiliation will be filtered based on the published item (if one was
specified), the subscription status and originating node.

@param notification the message to send containing the event notification.
@param notifySubscriptions list of subscriptions that were affected and are going to be
       included in the notification message. The list should not be empty.
