Hi Paul.

I take well your points, but they are document-centric, I I don't beleive
they represent current practices of Web design.

One only has to take a look at the source of Web sites out there to see
that current use of HTML is a horrible mess, and are solely concerned with
the appearence of the site, with little regard for the semantic correctness
of the HTML.

Dreamweaver and NetObjects Fusion barely encourage the useage of Hn tags,
and don't encourage the use of ADDRESS, CITE tags etc at all. What they do
encourage is an appearence focused design, with emphasis on layer
positioning and manipulation... semantics break down completely here. By
you're light they are broken, but the average Web designer simply doesn't
care. He has prototyped his designs in PhotoShop is is seeking to achieve
the best possible interpretation of this in the browser.

He may resort to Flash, in which case you've lost him completely.

Why do I think aural presentation objects would be supported?.... Becasue
quite simply it allows the Web Designer to do cool things... it is the sole
reason why I started playing with MS Agents, and it is the sole reason why
I tried to get our product manager to allow me to incorporate
text-to-speach and voice recognition into our intranet application.

What you are also suggesting is the intermixing of two radicaly different
presentation....

I migh produce a corporate from page for a site, that is highly graphical,
the aural inference from whch by be near zero, but there might be lots to
say about it. If I can seperate visual presentation from aural presentation
I *can* say lots about it to the listener.

Putting my Web Designer hat on rather than my knowledge management hat on
mixing visual and aural presentation is a monumentaly *bad thig* and is
doomed to failure for anything but a very simple document of data, and
wholy inappropriate for the desing of Web sites.

Cheers
     Guy.

As far as I know, aural presentation of Web pages works *today*.

HTML *allows* you to do things properly and also makes that relatively
easy to do. For instance MSWord 2000 outputs H1s, H2s, etc. for headings.
So does DreamWeaver. I don't know a lot about other tools.
Formatting objects *have no concept* of an H1 and an H2 so they don't even
give users the option of doing things in an accessible manner -- unless
they make a whole 'nother aural stylesheet (which we know they are not
likely to do).

You don't. But then no major tools I know of generate just SPANs and DIVs.
You could point to a tool that did and say: "that tool is broken." But a
tool that used the same FO tag for paragraphs and headings would be *doing
the right thing*. That's a problem.

In a world of unlimited resources, maybe. In this world, not a chance. How
much do you know about the proper aural specification for sight impaired
people? How much research have you done? I know what I know: "use good,
semantic HTML and let the software handle it."
That's pretty much the jist of what the experts say also:
http://www.w3.org/TR/WAI-WEBCONTENT/
Of their 14 guidelines not a single one says: "Go out of your way to use
special technologies designed for impaired viewers." Most of them say,
rather: "use the technologies that you would ordinarily use, but use them
carefully and properly." "alt" text is the only counterexample and we know
how wildly popular THAT has been.

We don't need to go back to HTML if the formatting objects are made
accessible.
