I could make a very compelling argument that Open XML has done more to revive the reputation of international standards than any other standard before it.
i doubt such an argument can be made anywhere except in warm fantasies of those oblivious to decades of international standards work. a reasonable reading of the events, arguments and objections around this particular "standard" suggests iso's reputation, such as it was since the heady days of iso/osi, is worse off than before; there has been significant complaints that microsoft, consistent with its history of monopolistic aggressiveness, has abused the standards fasttrack process to push out a specification that it can manipulate to compete against a well-specified, open iso standard it does not like. [canada, i am proud to say, voted against this faux-standard precisely because of this]
being a microsoft toady is not the kind of reputation iso needs.
