For some reason, the Gell-Mann Totalitarian Principle sprung into my mind when I read this. "Everything which is not forbidden, is compulsory." But the HTML specs, recklessly defying quantum physics, do not follow that principle. Instead... "Everything which is not defined, is forbidden." For the same reason, xmlns:foo attributes aren't allowed in HTML4 either.
