Yeah, changing the spec to allow 'all' to be special within a list
makes sense to me.

I'm not sure if it makes sense for 'none', though, but I guess
there's no harm, and it makes things more consistent.  (Flipping a
property to 'none' could save authors from having to remove an entry
from parallel lists for the other properties.)
