      notification, which informs the receiver of changes in the VNF
      lifecycle caused by a VNF LCM operation occurrence. The support of the
      notification is mandatory.
      This notification is produced when there is a change in the VNF
      lifecycle caused by a VNF LCM operation occurrence, including:
      * Instantiation of the VNF
      * Scaling of the VNF instance (including auto-scaling)
      * Healing of the VNF instance (including auto-healing)
      * Change of the state of the VNF instance (i.e. Operate VNF)
      * Change of the deployment flavour of the VNF instance
      * Change of the external virtual links of the VNF instance
      * Termination of the VNF instance
      * Modification of VNF instance information and/or VNF configurable
        properties through the "PATCH" method on the "Individual VNF instance"
        resource
      If this is the initial notification about the start of a VNF LCM
      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.
