This schema describes the Webcentric User layout markup language which allows you to define which layouts end-users can access in an application. Once you have designed and implemented a layout, you must include it in the configuration so that it is available to end-users.
The configuration allows you to: add layouts that always appear when the application starts up (the user cannot close such a layout); add layouts that do not appear when the application starts up (the user can manually open such a layout, for example from a menu), and can then close it again; override (for test purposes) the above behaviours for specific users.
