        This choice defines the method for reporting collected performance

        metrics to MnS consumers as well as the parameters for configuring the

        reporting function. It is a choice between the control parameter

        by the MnS producer and, on condition that an appropriate subscription

        is in place, inform the MnS consumer about the availability of new

        files and the file location using the notifyFileReady notification.

        In case the preparation of a file fails, "notifyFilePreparationError"

        In case the preparation of a file fails, 'notifyFilePreparationError'

        shall be sent instead.

        described for the case that only the 'fileReportingPeriod' is present.

        In addition, the MnS producer shall create on behalf of the MnS

        consumer a subscription, using "NtfSubscriptionControl", for the

        notification types "notifyMOICreation" and "notifyMOIDeletion" related

        to the "File" instances that will be produced later.In case an existing

        subscription does already include the "File" instances to be produced,

        subscription does already include the 'File' instances to be produced,

        no new subscription shall be created. The

        'notificationRecipientAddress' attribute in the created

        'NtfSubscriptionControl' instance shall be set to the value of the

        'notificationRecipientAddress' in the related 'PerfMetricJob'. This

        feature is called implicit notification subscription, as opposed to the

        case where the MnS consumer creates the subscription (explicit

        notification subscription). When the related "PerfMetricJob" is

        deleted, the "NtfSubscriptionControl" instance created due to the

        notification subscription). When the related 'PerfMetricJob' is

        deleted, the 'NtfSubscriptionControl' instance created due to the

        request for implicit subscription shall be deleted as well.
