RE: XHTML+RDFa and @lang

Do both specs reference BCP 47?  If not, alignment is unlikely.

It would... except that we have no standing to say anything about how an

HTML UA behaves.  Of course that is how it would behave in the real 
world.  The guidance to content authors is to ensure that these 
attributes are always both declared and both have the same value if the 
document is to be delivered to HTML and XHTML user agents.

I would probably be comfortable adding "When both attributes are present

on an element, authors SHOULD ensure they have the same value."  Would 
that help?
