If I put 

<TITLE>This is the Title</TITLE>
<GENERATETOC>
<H1>...
<H1>...

Then the structure *includes* the TOC to me, just as if I put:

<P>For more information on this, please see <GENERATEREFERENCE ID="Section.1">
or <OBJECT SRC="toc.html"> . It is irrelevant whether it exists as a physical 
file somewhere, if it can be predictably rendered.

But in most cases, the list bullet is "rendered" as another textual object on
the client. It is "generated text" that the author expects, in the same way
that a reference or table of contents is.

See above.

Indexers can index the document. Since the TOC doesn't include any text that
isn't also in the document, having them indexed separately just seems like a
way of promoting superfluous hits of the type that really annoy me.

Downlevel browsers will have to be taken care of, for a while, but *allowing*
TOC generation on the client does not in any way make it impossible or 
dificult to do it at the server side.

Right. Because they can be generated at the client. Which is why we should also
not ship around TOCs.

So we might as well give authors the option of letting the user agent
do the work since the output of the process is totally predictable and non-
creative like *other style issues*.
