Language::isKnownLanguageTag() – Checks that the language tag is known to MediaWiki. This basically means that we know the name of the language in English or in another language. Sources of known language codes are the built-in Names.php, the codes optionally added through the CLDR extension and the list of language names in English. ---- http://laxstrom.name/blag/2012/08/28/language-validation-in-mediawiki/ for background.
