I18N signature not working as described

I tried to set german language in the configuration with 'de_de' or 'de_DE', but only 'de' gives me german system messages.

Locale inheritance is not implemented in the framework because it involves directory searching and is thus expensive.

I see, thanks. But isn’t the guide a bit unclear then? I might get it wrong, but to me it says, language always has to be in LanguageID_RegionID format.

Yes, I had the same impression. This is true for i18n (see directory), but most of the current framework translations use single LanguageID.

yeah, I will update the guide to make it clearer. Thanks!

I updated the guide. The code is not changed.
