I can't see anything to indicate that UND means anything more than the language
isn't stated; whether because the tagger is ignorant or just isn't saying.
Likewise with the empty string for xml:lang.

The use of the empty string rather than UND matches the RFC "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."
