  InstantiateVnfRequest:
    description: >
      This type represents request parameters for the "Instantiate VNF" operation.

      NOTE 1:	The indication of externally-managed internal VLs is needed in case 
              networks have been pre-configured for use with certain VNFs, for instance 
              to ensure that these networks have certain properties such as security or 
              acceleration features, or to address particular network topologies. 
              The present document assumes that externally-managed internal VLs are 
              managed by the NFVO and created towards the VIM.
      NOTE 2:	It is possible to have several ExtManagedVirtualLinkData for the same VNF 
              internal VL in case of a multi-site VNF spanning several VIMs. The set of 
              ExtManagedVirtualLinkData corresponding to the same VNF internal VL shall 
              indicate so by referencing to the same VnfVirtualLinkDesc and externally-managed 
              multi-site VL instance (refer to clause 4.4.1.12).

    description: >
      This type represents a VNF instance.

      NOTE:	Clause B.3.2 provides examples illustrating the relationship among the different run-time 
            data types (CP, VL and link ports) used to represent the connectivity of a VNF.

      NOTE 1:	Modifying the value of this attribute shall not be performed when conflicts exist between 
              the previous and the newly referred VNF package, i.e. when the new VNFD is changed with 
              respect to the previous VNFD in other aspects than merely referencing to other VNF software 
              images. In order to avoid misalignment of the VnfInstance with the current VNF's on-boarded 
              VNF Package, the values of attributes in the VnfInstance that have corresponding attributes 
              in the VNFD shall be kept in sync with the values in the VNFD.
      NOTE 2:	ETSI GS NFV-SOL 001 specifies the structure and format of the VNFD based on TOSCA specifications.
      NOTE 3:	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.
      NOTE 4:	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. The defined initial values can be declared in the VNFD, and/or, in case of "metadata", 
              obtained from the "CreateVnfRequest" structure. Child attributes of "vnfConfigurableProperties", 
              "metadata" and "extensions" that have no defined 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.
      NOTE 5:	It is possible to have several ExtManagedVirtualLinkInfo for the same VNF internal VL in case of a 
              multi-site VNF spanning several VIMs. The set of ExtManagedVirtualLinkInfo corresponding to the same 
              VNF internal VL shall indicate so by referencing to the same VnfVirtualLinkDesc and externally-managed 
              multi-site VL instance (refer to clause 5.5.3.3).
      NOTE 6:	Even though externally-managed internal VLs are also used for VNF-internal connectivity, they shall 
              not be listed in the "vnfVirtualLinkResourceInfo" attribute as this would be redundant.

          These attributes represent values that are stored persistently in the VnfInstance structure
          and that correspond to configuration parameters of the VNF instance.
          
          Modifying these attributes affects the configuration of the VNF instance either directly 
          (if the VNF instance is in INSTANTIATED state at the time of the modification) or as part 
          of the subsequent VNF instantiation operation (if the VNF instance is in NOT_INSTANTIATED 
          state at the time of the modification).
          
          Configurable properties referred in these attributes are declared in the VNFD. The declaration 
          of configurable properties in the VNFD can optionally contain the specification of initial values. 
          See notes 2, 3 and 4. The VNFM shall reject requests to write configurable properties that are 
          not declared in the VNFD with a "422 Unprocessable Content" error response as defined in clause 
          6.4 of ETSI GS NFV SOL 013.
          
          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.

          These configurable properties can be initialized with default values from the VNFD (see note 4).

          Configurable properties can be modified with values passed in the request structures of certain 
          LCM operations, such as the InstantiateVnfRequest structure.
          
          Further, these configurable properties can be created, modified or deleted with the PATCH method.
          In addition, the provisions in clause 5.7 shall apply.

          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 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. See notes 2 and 4. 
          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 (see note 4) or with values 
          passed in the CreateVnfRequest structure (see clause 5.4.2.3.1).
          
          These attributes can be created, modified or removed with the PATCH method.

        description: >
          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 notes 2 and 4. The VNFM shall reject requests to write extension attributes 
          that are not declared in the VNFD with a "422 Unprocessable Content" 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 (see note 4).
          
          These attributes can be modified with values passed in the request structures of certain LCM operations, 
          such as the InstantiateVnfRequest structure.
          
          Further, these attributes can be created, modified or deleted with the PATCH method.
          
          In addition, the provisions in clause 5.7 shall apply.
