This set of sub-tests examines the level of support for three RFCs, 2318 (CSS mime type), 2068 (HTTP 1.1), and 1521 (MIME), as well as testing for compliance with Section 14.2.1 of the HTML4.0 specification. See also Test 41 of Part I of the ImportTest.
Test 66a works by setting the default style language of the
document to "text/nonsense", using a real HTTP
header. This should cause UAs to think "What's this then?
'text/nonsense'? But I do not understand this language! I had better
ignore any style attributes used, lest I make a fool of
myself".
(66a). Style set by style attribute.
If the test is red, then the browser is buggy (B). If the test is unstyled, then the browser is maybe correct (M).Browsers may be upgraded to full pass status (Y) if they pass test 41 and either I notice or someone tells me.
