      operation occurrence, it is assumed that the notification is sent by the
      VNFM before any action (including sending the grant request) is taken,
      however, after acknowledging the LCM operation request to the consumer.
      Due to possible race conditions, this does not guarantee that the
      notification will also arrive at the NFVO before the grant request, and
      after the acknowledgement of the operation. It is not an error if the
      "start" notification, the grant request and the LCM operation
      acknowledgment arrive out of order at the NFVO, and the NFVO shall be
      able to handle such a situation.
      If this is a notification about a final or intermediate result state of
      a VNF LCM operation occurrence, the notification shall be sent after
      all related actions of the LCM operation that led to this state have 
      been executed. The new state shall be set in the VnfLcmOpOcc resource
      before the notification about the state change is sent.
