Language information is also used by speech synthesis software
(e.g. screen readers), so whatever mechanism you use must
be unambiguous for this type of software.
(Before anyone asks: no, you can't expect screen readers to
perform automatic language recognition; they want to get the
language information from the browser.)

I'm not aware of any speech synthesis software used by
persons with disabilities that supports xml:lang.
(This may be because browsers don't support it; if you
have sections with xml:lang="en" in an XHTML document
and :lang(en) { ... } in the CSS for that document,
the style rules won't take effect until you duplicate
'xml:lang="en"' as 'lang="en"'. (I admit I haven't looked
into the effects of different MIME types here.) )


Best regards,
