    IMPORTANT: Please note that this file might be not aligned to the current
    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.

        Subscribe.
        The POST method creates a new subscription.
        This method shall follow the provisions specified in the tables 7.4.4.3.1-1 and 7.4.4.3.1-2
        for URI query parameters, request and response data structures, and response codes.
        As the result of successfully executing this method, a new "Individual subscription" resource
        as defined in clause 7.4.5 shall have been created. This method shall not trigger any notification.
        Creation of two "Individual subscription" resources with the same callback URI and the same filter
        can result in performance degradation and will provide duplicates of notifications to the NFVO,
        and might make sense only in very rare use cases. Consequently, the VNFM may either allow creating
        a new "Individual subscription" resource if another "Individual subscription" resource with the
        same filter and callback URI already exists (in which case it shall return the "201 Created" response code),
        or may decide to not create a duplicate "Individual subscription" resource (in which case it shall return
        a "303 See Other" response code referencing the existing "Individual subscription" resource with the
        same filter and callback URI).
