There is a problem with the proposal below, which is that it
requires that the timing containment and ordering relationships
be congruous with the layout/formatting (box model) relationships;
however, in general, this is not the case. This can potentially
be handled, albeit, with a loss of generality, by flattening out
either the timing model or the formatting model, i.e., assigning
fixed times or positions to every element.

As an example, consider the case:

<ol>
  <li>Gold Winner</li>
  <li>Silver Winner</li>
  <li>Bronze Winner</li>
</ol>

vs

<seq>
  <p>Bronze Winner</p>
  <p>Silver Winner</p>
  <p>Gold Winner</p>
</seq>

The natural layout order turns out to be reverse of the natural
timing order.

Regards,
Glenn
