closePointOut

closePointOut is used in response to a pointOut notification for formally notifying the system that the notification has been processed by the receiver.
This remains a local action between the receiver and his/her system without any OLDI equivalent message.
The originator controller is capable of ending the point session, while the designated controller is capable only to remove his OEs from the recipient list (and if there is no more recipient, the point session is ended). The exception being that it is not possible to end a point session in another OLDI ATSU because OLDI considers the "point" as a one shot distribution..
