Lack of interest Add missing HTML Languages


Well-known member
In ACP admin.php?languages I can edit a language en set their html locale like English (UK) will result in <html lang="en-GB"> in html source code.

Can you please add also following languages in xf, so they will be selectable in the list? If it's not already included in newest xf version, I didn't check. The reason is one more small SEO point when a forum aims for only one specific german speaking country. (At the moment i have to template modification it)

de-DE (German-Germany)
de-AT (German-Austria)
de-CH (German-Switzerland)
