      vnfConfigurableProperties:

          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. 
          This attribute can be modified with the PATCH method.

  ChangeExtVnfConnectivityData:
     description: >
       This type describes the information invoked by the NFVO to change the external VNF connectivity information
       maintained by the VNFM. The types of changes that this operation supports are:
       1) Disconnect the external CPs that are connected to a particular external VL, and connect them to a different
       external VL.
       2) Change the connectivity parameters of the existing external CPs, including changing addresses.
       NOTE: Depending on the capabilities of the underlying VIM resources, certain changes (e.g. modifying the IP
       address assignment) might not be supported without deleting the resource and creating another one with
       the modified configuration.
       This type shall comply with the provisions defined in Table 6.5.3.33-1.
