That _would_ be a worse example of this if there are existing pages
which have <ol reversed> and which are relying on it doing absolutely
nothing.  Do you know of any such pages?

Note there is a difference between:

* Existing content + HTML 5 browser -- an existing page (possibly
  written years ago, possibly unmaintained) displays consistently in
  existing browsers, but a browser following HTML 5 would display it
  differently.

* Existing browser + HTML 5 content -- HTML 5 introduces a new feature,
  not implemented in current browsers.  An HTML-5-aware author can
  choose to use this or not; he'd probably want to take into account his
  audience and whether there are any work-arounds for older browsers
  (such as JavaScript which spots 'reversed' attributes and re-orders
  <li>s accordingly).
