I'm saying, again, that we should compare the world as t would be with W3C recommendations as we have proposed with the world as it would be without such recommendations and ask whether the *difference* between these two situations is something consistent with W3C values / goals. Anything that remains the same between these two outcomes is irrelevant to the discussion. ...Mark > > > > > > With EME we're hoping to make it *easier* to support more >>>> platforms, >>>> so if anything EME will have the opposite effect. >>>> >>> >>> At best this will change nothing at all in terms of supported >>> platforms.
