I believe this is correct.

Agreed.  We can achieve this through updating the errata document 
immediately.  I will try to draft some errata text and propose it for 
discussion at tomorrow's regular meeting.

XHTML 1.1 and XHTML Basic 1.1 will soon re-introduce @lang with 
prioritization rules.  We anticipate ALSO introducing @lang into 
XHTML+RDFa in the next revision - obviously with the same rules.  It is 
important that people use @lang because of legacy issues with a number 
of user agents and assistive technologies.
