Inactive Knowledge Profile Options
Note: This topic is only applicable to Fusion Service Knowledge
            Management with Redwood User Experience.
        When you enable Knowledge features by setting profile options in the setup and
            maintenance area, you may see profile options that aren't mentioned in any of the setup
            topics. These options have CSO_NOTIFICATIONS in their option code (for
            example, CSO_NOTIFICATIONS_EXPIRED). They're inactive, and don't enable
            any available functionality in the Knowledge Management offering.
