To follow up on this one as well -- here I also prefer the text in
the CR over the text in the editor's draft, although my feelings are
not as strong as in the other case.  I think giving authors the
ability to do if/else with a guarantee that at exactly one of the
options will be applied is probably more valuable than giving
authors the ability to detect whether the media feature is correctly
detected.  (It would be better to be able to do both, but I don't
see a trivial way to do that.)  That said, I could be convinced

I wrote a testcase to try to test this:
The only browsers I've found that support not (Opera 9.5 beta 1 and
Safari 3.1) make it yellow, which agrees with the CR, not the
editor's draft.
