        Creation of two subscription resources with the same callbackURI and the same filter can result in performance
        degradation and will provide duplicates of notifications to the OSS, and might make sense only in very rare use cases.
        Consequently, the NFVO may either allow creating a subscription resource if another subscription resource with the
        same filter and callbackUri already exists (in which case it shall return the "201 Created" response code), or may decide
        to not create a duplicate subscription resource (in which case it shall return a "303 See Other" response code referencing
