very nice and thanks for contributing what looks like a good resource! I'd be interest to know how you went about organizing the research for this? I've read webkits WebCore source and its pretty enlightening did you go that way or was this really dissecting the agggh incredibly intersting spec docs?

Also as a minor note, I know this a rough draft but have you thought about the code syntax styling? Its not that its bad at all, its just I think it could be more readable with some color differntiation :)
