The HTMLwg just decided that http-equiv="Content-Language" should be illegal.

http://www.w3.org/mid/4D84B9B4.3040809@intertwingly.net

As a result, here is an updated proposal (I only added this string: "(which is
non-conforming HTML5)":


]]
    Polyglot markup avoids that the language of the root element is set by
HTML5's fallback language mechanism as this mechanism is not required to work
in XML.

    [NOTE:] HTML5's fallback language mechanism activates whenever the root
element is lacking language attributes. But for the mechanism to actually set a
fallback language, it has to locate an http-equiv="Content-Language" meta
element (which is non-conforming HTML5) or a HTTP Content-Language: header 
(anyone of them, but meta element is considered first) whose content value is
no more and no less than exactly a one language tag, see the <a
href="http://www.w3.org/TR/html5/elements#language">language determination
rules</a> of [HTML5].
