| * - name: The human-readable language type identifier. | |
| * - description: A description of the language type. | |
| * - locked: A boolean indicating if the user can choose whether to configure | |

| * initialize this language. If locked is set to TRUE and fixed is set, it | |
| * will always use the specified methods in the given priority order. If not | |
| * present and locked is TRUE then language-interface will be | |
| * used. | |
