The fact that this works anywhere at all today implies that little, if
any, changes to browsers is required in order to support this. Is
that a fair statement?
I've not taken a look at the code, but have taken a quick glance at
the output using IE8.0.7000.0 beta, Safari 3.2.1/Windows, Chrome
188.8.131.52, Opera 9.63, and Firefox 3.0.5.
The page is different (as in less functional) under IE8 and Safari.
Is there something that they need to do which is not already covered
in the HTML5 specification in order to support this?
