I don't think that's a fair representation of what I wrote -- I did not 
use quotation marks.
You've framed your proposal as a means to obsolete longdesc.

You've repeatedly stated that "the aria-describedby attribute" is a 
"better alternative" and that longdesc should be kept out of the HTML5 spec.

This meet in the middle strategy does not replace longdesc. It's been 
four years since the issue was raised.

Gregory Rosmaita wrote about the two semantic qualities of longdesc that 
are unmatched:

    1. A direct, reusable programmatic determinable mechanism to a
       long description of an image without a forced visual
       encumbrance or default visual indicator.

    2. A method to reference a longer description of an image, without
       including the content in the main flow of a page.

The @hidden attribute meets in the middle -- it handles #1 but breaks 
compatibility with existing browsers and ATs.

As John Foliot writes:
"What is at issue is what happens to content not visible on screen: the 
Accessibility APIs flatten the content to string text... Hidden content, 
whether referenced by ARIA attributes or not, cannot (should not) 
support focusable content."

Mozilla, Google and Apple do not support older hardware. I have a 
perfectly functioning laptop that will only run Firefox 3.x. This is a 
real concern for me and many millions of users. We can't simply tell 
people to meter 20megs of bandwidth to upgrade their browser. Some of us 
over-achievers may still use off-screen positioning via CSS. It really 
depends on the context and content.

We have a disconnect here that can't truly be resolved: "browsers today 
have problems if the @hidden contents contains 'rich content'. But 
that's browsers today. Our goal for the HTML5 spec shouldn't be to 
document best practices for todays browsers."

This is disconnected from the computer re-use practices of most of the 
world, as well as WCAG and the principles that the UAAG put forward.

Silvia did try to find a middle ground here, suggesting that 
aria-hidden="false" have more meaning:

But that breaks the boundaries of ARIA -- that it should not affect the 
way in which the UA operates.

The problem with changing focus semantics on @hidden is that it "breaks 
the web", to borrow the lingo often used by your team. The problem with 
dropping @longdesc is that it breaks compatibility, without an available 
superset semantic, a hypernym.

VHA Section 508 Office chimed in:

The Association of American Publishers commented on the issue:

In the AAP post, I explored aria-describedby and aria-flowto as possible 
long term mechanisms.
That's the thread where my mind finally turned, and I saw that @longdesc 
should not be deprecated.

I fully support the ARIA mechanisms for long term use.

I can't support deprecating @longdesc. There is far too much evidence 
that it should remain a supported feature for <img> in HTML. There's far 
too much support behind it. The arguments are on the table; and for most 
of the arguments against longdesc, I'd simply say: "Hey, you should use 
some ARIA while you're at it."

Now if you want to aim for HTML6, that's fine. SVG2 is likely to 
completely break compatibility. Let's allow that with HTML6 as well. In 
the meantime, lets get HTML5 published in the near future. That's not 
what the HTML editor is looking to do, but a lot of WG participants are.

I'd imagine the chairs actually intend to publish an HTML5.

And as for putting words in the HTML editor's mouth; I did not use 
quotation marks, and he has repeatedly stated that he is working on a 
living document, that he does not approve of the publishing process, and 
he moved away from the term HTML5 in response to the W3C using the term 
in publicity. There is sufficient public record on this issue. My 
statement about the HTML5 editor is not libelous. He has a different 
perspective, and that's OK, but it is different.

Jonas, you have a different perspective too. That's OK, too. Multiple 
viewpoints are a good thing. We are fleshing out real issues in this
