          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 not changed with respect 
          to the previous VNFD apart from 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.

          Additional VNF-specific attributes that provide the current values 
          of the configurable properties of the VNF instance.
          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 shall be declared 
          in the VNFD. 
          The declaration of configurable properties in the VNFD can optionally 
          contain the specification of initial values. 
          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.
          This attributeThese attributes can be modified with the PATCH method.

          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 VNF provider foresees shall be declared in the VNFD. The VNFM shall 
          accept requests to write metadata that are not  are declared in the VNFD.  

          These attributes can be initialized with default values from VNFD and/or with values 
          passed in the CreateVnfRequest structure (see clause 5.5.2.3).

          Additional VNF specific attributes that affect the lifecycle management of this

          These attributes represent values that are stored persistently in the VnfInstance 
          structure for consumption by the VNFM, or by the lifecycle management scripts 
          during the execution of VNF lifecycle management operations. 
        
          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.

          All extensions that are allowed for the VNF shall be declared in the VNFD.
          This attribute can be be initialized with default values from VNFD and/or 
          with values passed in the InstantiateVnfRequest structure (see clause 5.5.2.4).

          A value initialised with default values from the VNFD can be updated with values 
          passed in the InstantiateVnfRequest structure.

          Further, these attributes can be modified with the PATCH method.
