xml:lang="" vs meta Content-Language
Assertion holds if you see green below.
This test is only valid if the user agent recognises the meta Content-Language and html xml:lang declarations, and :lang works.
| Ignore this test. (:lang not supported) |
Assertion: If the meta Content-Language element contains a language declaration but the html element uses an empty xml:lang attribute, the UA will not recognize the language declared in the meta Content-Language element.
Notes:
Red means the HTTP had precedence.
