HTTP header and meta element
Test passes if you see green below, and no message to ignore it.
This test is only valid if the user agent recognises the HTTP and meta declarations, and :lang works.
|Ignore this test. (:lang not supported)|
Assertion: If there is a conflict between the language declarations in the HTTP header and the Content-Language meta element, the UA will recognize the language declared in the meta element.
Red means the HTTP declaration had precedence.
