I take in that you mean the text/html case.
That would be possible in browsers whose DOM implementations need to
do ugly XML-hostile things for text/html anyway. However, other types
of programs processing HTML5 using XML tools would have to be allowed
to consider xml:lang in text/html non-conforming and trashable,
because what you suggest violates basic assumptions that XML
processing software is supposed to make or even enforce.
