Ah, it is. I could not find a definition for it. But the HTML spec
says the lang codes used must be as defined in RFC1766 which
has now been obsoleted by 3066 which states
5. You SHOULD NOT use the UND (Undetermined) code unless the protocol
in use forces you to give a value for the language tag, even if
the language is unknown. Omitting the tag is preferred.
