The DELETE RMS_DATABASE command deletes a logical RMS database
    element from the repository.

    If the RMS database element is controlled, CDO freezes previous
    versions and allows you to delete only the highest visible
    version. If the RMS database element is uncontrolled, CDO deletes
    the highest visible version unless you specify another version
    number.

    Before you can issue the DELETE RMS_DATABASE command, you must
    have deleted the associated physical RMS database element with
    the DELETE DATABASE command.
