Minor Description
If you set one base language (e.g. FR)and you input some texts/pages/... and if you insert a new similar local language (e.g. FR_CH) and desactivate the main FR, all the texts, pages,... input in FR appears in FR_CH. Sometimes the engines use this a a real default value (e.g. Page properties), sometimes not (e.g. Navigation container which displays nothing even if a value is displayed on the page). The correct version should be to display nothing excepted null value (excepted if the mix language mode is activated of course).
Finally if you have both languages (FR desactivated and FR_CH activated as you can not suppress any more languages) the language mapping feature is not activated any more (in opposite if you only have FR_CH and this will automatically map the language to FR). In such a case, we may perhaps also map FR_CH to FR if FR is notactivated any more.
