This sub-test examines the level of support for three RFCs, 2318 (CSS mime type), 2068 (HTTP 1.1), and 1521 (MIME), as well as compliance with Section 14.2.1 of the HTML4.0 specification. See also Test 64 of the ImportTest.
Test 69a works by setting the content type of a linked stylesheet
text/css; charset=ISO-8859-1" using both a real HTTP
header and the
type attribute on the
element. This should cause UAs to accept that stylesheet, as it is a
valid mime type.
If the test is unstyled, then the browser is buggy (B). If the test is green, then the browser is a maybe (M). Browsers may be upgraded to full pass status (Y) if they pass test 64 and either I notice or someone tells me.
