The spec says that it may be used that way only in HTML. Therefore,  
an algorithm that maps conforming HTML5 to conforming XHTML5 must  
remove it in order to keep the result conforming.

Not according to the spec. It says "lang (HTML only) and xml:lang  
(XML only)". (I like it the way it is with only one language  
attribute on each side.)

BTW, the spec also says: "If both the xml:lang attribute and the lang  
attribute are set, user agents must use the xml:lang attribute, and  
the lang attribute must be ignored for the purposes of determining  
the element's language."

Shouldn't lang take precedence in HTML?
