Website authors, designers and developers will probably find this a (far) better reference to use:
Matter of fact, that's on the very short list of sites I don't have bookmarked... because I've got the name memorized ;)
But the question remains: If there is no standard, what does a "conforming user-agent" conform to? There's a world of difference between This browser does everything that CSS 2.1 says a browser is supposed to do and This browser does everything that was posted in such-and-such location on such-and-such date, but we make no promises about rules from the day before or the day after.
It would be fine if CSS and HTML only moved in one direction, so today's standard includes yesterday's. You can go a hell of a long way on Euclid and Newton; if a browser can handle sites built today, it should have no trouble with sites built in 1997.
But things are falling off the far end too. One day you wake up and discover that <tt> and <u> are gone. And next week your browser says They're no longer in the standard, so I don't have to recognize them.
