The main request should not include the CSS type. The requests for
style sheets should only list the CSS type. Requests for images
should only list image types.

It is rather sad that the supported image formats do not include PNG.

Related issues: (space separated ids)

WG Notes: This follows from the fact that PNG support isn't as widespread as GIF or JPEG -- nothing personal at all against PNG.

Resolution: We think that the request headers indicate general capabilities not specific capabilities for any particular request. In the case of the "main" request, it cannot be said for sure that the resource under test is not a css resource. The tester takes no view aobut the format of a resource under test when it requests it, it is only after it receives it that it checks that it is valid HTML etc. In general we believe this is consistent with User Agent behaviour which is not to assume that a resource is of any particular format. PNG is not included in the request header because it is defined as being unsupported by the DDC. That in turn results from support not being as widespread as other formats.
