{{lang}} uses the Lua functionlang()Module:Lang. That module also supports all of the{{lang-??}} templates using the Lua functionslang_xx_inherit() andlang_xx_italic(). The module has other functions that may be useful. The function selector parameter|fn= tells module:lang which function to execute. The available functions are:
is_ietf_tag – returnstrue if the providedIETF language tag is valid; nil else
{{lang|fn=is_ietf_tag|nv}} →true←
{{lang|fn=is_ietf_tag|xx}} →←
is_lang_name – returnstrue if the provided language name is valid; nil else
{{lang|fn=is_lang_name|navajo}} →←
{{lang|fn=is_lang_name|xxxxx}} →←
