Still what we now have is one promice and one questionably enforceable quasilegal statement. And you know what worth are MS promises. OK guys, however it's high time somebody did a sensible comparison: - what can be done and what can't with respective formats - what is the quality of documentation (you know, there are subtle details about layout and formatting rules, tu just explain what tags mean is not enough). I guest reasonable docs about format should be of size of a dozen W3 specs. - are there any inherent performance / scalability issues wrt to every format information architecture - which one is friendlier as a general information container taking bigger picture (besides office) into acount. (Free hint: whoever first publishes a compheresive guide to those formats will be a king of the hill for some time)
