        This method terminates an individual subscription.
        As the result of successfully executing this method, the "Individual 
        subscription" resource shall not exist any longer. This means that no 
        notifications for that subscription shall be sent to the 
        formerly-subscribed API consumer. 
        NOTE:	Due to race conditions, some notifications might still be 
        received by the formerly-subscribed API consumer for a certain time 
        period after the deletion.
