          Specifies the details to terminate VNF instance(s).

          It shall be present only if updateType = "REMOVE_VNF"

          and if the VNF instance(s) is(are) to be terminated as

          part of this operation.

          is terminated by the NFVO.

          For each of the referred vnfInstanceId in the terminateVnfData,

          there shall be a corresponding value in the removeVnfInstanceId.
