      This type represents a VNF lifecycle management operation occurrence
      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 shall be triggered by the VNFM 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 connectivity 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 as
      part of the LCM operation. Due to possible race conditions, the "start"
      notification, the grant request and the LCM operation acknowledgment can
      arrive in any 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.

          Current values of the configurable properties of the VNF instance. 
          Configurable properties referred in this attribute are declared in
          the VNFD.
          ETSI GS NFV-SOL 001 specifies the structure and format of the VNFD
          based on TOSCA specifications.
          VNF configurable properties are sometimes also referred to as
          configuration parameters applicable to a VNF. Some of these are set
          prior to instantiation and cannot be modified if the VNF is
          instantiated, some are set prior to instantiation (are part of
          initial configuration) and can be modified later, and others can be
          set only after instantiation. The applicability of certain
          configuration may depend on the VNF and the required operation of
          the VNF at a certain point in time.
          These configurable properties include the following standard
          attributes, which are declared in the VNFD if auto-scaling and/or
          auto-healing are supported by the VNF: 
          * isAutoscaleEnabled: If present, the VNF supports auto-scaling. If
            set to true, auto-scaling is currently enabled. If set to false,
            auto-scaling is currently disabled. 
          * isAutohealEnabled: If present, the VNF supports auto-healing. If
            set to true, auto-healing is currently enabled. If set to false,
            auto-healing is currently disabled.

          Additional VNF-specific attributes that provide metadata describing the VNF instance.
          These attributes represent values that are stored persistently in the VnfInstance structure
          for consumption by functional blocks that invoke the VNF lifecycle management interface.
          They are not consumed by the VNFM, or the lifecycle management scripts.
          Modifying the values of these attributes has no effect on the VNF instance, it only affects
          the information represented in the VnfInstance structure.
          Metadata that are writeable are the VNF provider foresees are expected to be declared in the VNFD.
          The declaration of metadata in the VNFD can optionally contain the specification of initial values.
          The VNFM shall accept requests to write metadata that are not declared in the VNFD.
          These attributes can be initialized with default values from the VNFD or with values
          passed in the CreateVnfRequest structure (see clause 5.5.2.3).
          This attributeThese attributes can be created, modified or removed with the PATCH method.

          ETSI GS NFV-SOL 001 specifies the structure and format of the VNFD based on TOSCA specifications.
          Upon creation of the VnfInstance structure, the VNFM shall create and initialize all child attributes
          of "vnfConfigurableProperties", "metadata" and "extensions" that were declared in the VNFD with
          a defined initial value. Child attributes of "vnfConfigurableProperties", "metadata" and "extensions"
          that have no declared initial value shall not be created, in order to be consistent with the semantics
          of the JSON Merge Patch method (see IETF RFC 7396) that interprets null values as deletion request.

          Additional VNF-specific attributes that affect the lifecycle management of this VNF instance.
          These attributes represent values that are stored persistently in the VnfInstance structure
          for consumption by the VNFM or the lifecycle management scripts during the execution of
          VNF lifecycle management operations.
          All extensions that are allowed for the VNF are declared in the VNFD. The declaration of an extension
          in the VNFD contains information on whether its presence is optional or required, and optionally
          can specify an initial value. See note 2 and note 4. The VNFM shall reject requests to write extension
          attributes that are not declared in the VNFD with a "422 Unprocessable entity" error response as defined
          in clause 6.4 of ETSI GS NFV-SOL 013.
          Modifying the values of these attributes has no direct effect on the VNF instance; however, the modified
          attribute values can be considered during subsequent VNF lifecycle management operations, which means that
          the modified values can indirectly affect the configuration of the VNF instance.
          These attributes can be initialized with default values from the VNFD or with values passed in the
          InstantiateVnfRequest structure (see clause 5.5.2.4).
          Attributes initialized with default values from the VNFD can be updated with values passed in the
          InstantiateVnfRequest structure.
          Further, these attributes can be created, modified or deleted with the PATCH method.

          Upon creation of the VnfInstance structure, the VNFM shall create and initialize all child attributes
          of "vnfConfigurableProperties", "metadata" and "extensions" that were declared in the VNFD with
          a defined initial value. Child attributes of "vnfConfigurableProperties", "metadata" and "extensions"
          that have no declared initial value shall not be created, in order to be consistent with the semantics
