        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 the existing subscription resource with the same filter and callbackUri).

        The API consumer can use this method to retrieve the list of active subscriptions for alarms related to an NS subscribed
        by the API consumer. It can be used e.g. for resynchronization after error situations.
        This method shall follow the provisions specified in the Tables 8.4.4.3.2-1 and 8.4.4.3.2-2 for URI query parameters,
        request and response data structures, and response codes.

            OSS/BSS may supply this parameter.
            All attribute names that appear in the FmSubscription and in data types referenced from it
            shall be supported by the NFVO in the filter expression.
