Hi again Steve

re:
... one principle is a thought experiment, the other is implemented and
used already,

Which of the proposals are already implemented? I thought that "<main>" was
a proposal for 5.1?

I urge anyone who thinks Ian's idea is worthwhile to define how it would
work in practice and get implementers interested in making it real.

Here's how the Hixon proposal may work:

tab -> (jump to) <header> ignore, skip -> (jump to) <nav> ignore, skip ->
(jump to) <aside> ignore, skip -> (jump to) <div id="gallery"> stop, allow
user to read/view;
next tab -> <div id="products"> stop, allow user to read/view;
next tab -> <aside> ignore, skip -> <div id="contactUs"> stop, allow user
to read/view;
next tab -> <footer> ignore, skip -> return to top....

Regards
Harry
