As long as the source document lends itself to it, I like to have actual
code to extract the data (I find it easier to write (and tweak next time around) the code than to do the extraction manually). But if you're volunteering to be css-mode's maintainer, it's your call.

I'd be happy to!

I might look into restoring the extraction code to ease the
maintaining job later on. At this point I just wanted to get css-mode
up to speed with CSS3 ASAP.

Other than that all 3 patches look good, feel free to install them.

Would if I could, but I don't have write access to the Emacs
repository.
