I would like to see support for implementing multiple languages in geodatabase domain descriptions, and the ArcGIS system automatically display the appropriate language configured for the client application, similar to a resource file implementation for UI labels and other items. More and more we are supporting multi-national companies that require this ability, and the workarounds I have seen for this are an obvious hack at best.
Example Domain:
code1 -- English Description -- French Description -- French Canadian Description -- Spanish Description....
code2 -- English Description -- French Description -- French Canadian Description -- Spanish Description....
