Personally I like this proposal a lot. Until the day that humans don't need to write HTML by hand (a day sadly further away than I would like), something like this would do a lot to aid both the readability and writability of HTML.
I suppose this could be dismissed as being unneeded because the class= is there for this purpose. That this proposal is only sugar, but sometimes sugar is important. This is the cleanest proposal I have seen to make HTML more expressive for such a common case. -- Jock Murphy Founder www.stufflabs.com
