    version of the ETSI Group Specification it refers to. In case of
    discrepancies the published ETSI Group Specification takes precedence.


    In clause 4.3.2 of ETSI GS NFV-SOL 003 v2.4.1, an attribute-based
    filtering mechanism is defined. This mechanism is currently not
    included in the corresponding OpenAPI design for this GS version. Changes
    to the attribute-based filtering mechanism are being considered in v2.5.1
    of this GS for inclusion in the corresponding future ETSI NFV OpenAPI
    design.

        Scale VNF to Level.
        The POST method requests to scale a VNF instance resource to a target level.
        This method shall follow the provisions specified in the tables 5.4.6.3.1-1 and 5.4.6.3.1-2
        for URI query parameters, request and response data structures, and response codes.
        The steps and conditions that apply as the result of successfully executing this method are
        specified in clause 5.4.1.2.
        In addition, once the VNFM has successfully completed the underlying VNF LCM operation occurrence,
        it shall reflect the result of scaling the VNF instance by updating the "scaleStatus" attribute
        in the representation of the "Individual VNF instance" resource.

            Shall be returned upon the following error: The API producer did not find a current representation
            for the target resource or is not willing to disclose that one exists.
            The general cause for this error and its handling is specified in clause 6.4 of ETSI GS NFV-SOL 013,
            including rules for the presence of the response body.
            Specifically in case of this task resource, the response code 404 shall also returned if the task
            is not supported for the VNF instance represented by the parent resource, which means that the task resource
            consequently does not exist.

            Shall be returned upon the following error: The operation cannot be executed currently,
            due to a conflict with the state of the resource.
            Typically, this is due to the fact that the VNF instance resource is in NOT_INSTANTIATED state,
            that another lifecycle management operation is ongoing, or that a required child attribute of
            the "extensions" attribute has not been set.
            Those attributes are marked as "required" in the VNFD.
