We need the numbers because some people have
auto-numbering turned on, and
the TOC numbers should correspond to the auto-generated numbers within the
headings.
As a user of auto-numbered headers, I'd be quite happy with
ordered lists inside ordered lists, like so:
<ol><li>Header A
<ol><li>Subheader a</li>
<li>Subheader b</li>
</ol></li>
<li>Header B</li>
</ol>
which generally appears along the lines of:
1 Header A
1 Subheader a
2 Subheader b
2 Header B
That seems pretty clear to me.
