[xml|lang="es"], xml:lang="es" with no @namespace
Ignore this test. (Namespaces are not supported for this format.)
You can only get meaningful results for this test if namespaces are supported for this format.
Test passes if you see green below.
Assertion: An xml|lang= selector with no @namespace declaration that matches an identical xml:lang attribute value will not produce styling.
If there is no message to the contrary above, the browser does support namespaces in selectors. If the test isn't green, this highlights a specific problem with xml:lang.
