Thank you for this beautifully-wrought argument.  Much of this I agree with.
Let me expand on a few points of divergence.

** summary

Yes, 'author proposes' is required for hotkey bindings.  This is needed both
for application-specific hotkeys and for getting the authors to identify the
hotspots whose access should be accelerated.

Yes, an element is needed because what is needed is a menu entry and
that needs to be internationalized, including essential markup such as <ruby>.

This is not to say we shouldn't be accelerating items based on their
roles.  Quite to the contrary.  Review the Table of Contents function
in the Mozilla Access Extension being developed in conjunction with
the 'role' work.

http://lists.w3.org/Archives/Public/wai-xtech/2005May/0011.html

And I suspect once we have it right, the default ToC will pick up headers
automatically without having to add 'role' qualification to them.

But the author-extension option needs to be there, duly integrated into
the event model.

Given the fact that SVG 1.2 Tiny is ahead of XHTML 2.0, we may be 
able to lose the 'access' attribute and element entirely in favor of 
an sXBL application before this format is done.

No, that would not be my first choice.

but it is a feasible syntax so long as the client-side management and
overriding of the UI-event bindings is duly specified and implemented.

The precedent is set in the XForms specification.

<quote>

accesskey

Optional attribute defines a shortcut for moving the input focus
directly to a particular form control . The value of this is a
single character which when pressed together with a platform specific
modifier key (e.g., the alt key) results in the focus being set
to this form control .

The user agent must provide a means of identifying the accesskeys
that can be used in a presentation. This may be accomplished in
different ways by different implementations, for example through
direct interaction with the application or via the user's
guide. The accesskey requested by the author might not be made
available by the player (for example it may not exist on the
device used, or it may be used by the player itself). Therefore
the user agent should make the specified key available, but may
map the accesskey to a different interaction behavior.

found by string searching 'accesskey' in:
http://www.w3.org/TR/xforms/index-all.html

If that functionality has been broken in this draft, we need to fix it.

In my theoretical model, the 'access' element is specifying a
pseudonym for the event DOMfocusIn(here) or in other uses
a pseudonym for DOMactivate(here).  This is a binding
that belongs in the 'views' layer of the DOM.  And since half
the accesskeys are actually intended as pseudonyms for firing
DOMactivate(here) there is not point for a half-replacement
with a dedicated element that only generates the focus
behavior.

What we need to get across is that we are really annotating
an event with a [menu entry and] hotkey.  Not an element.
And since the 'focusIn' and 'activate' events are already
well defined, we don't need any new constructs to create them.

There are two 'why' answers that to me validate the requirement
for an "author proposes" part to this "author proposes, user disposes"
key binding.

- one is application-specific verbs.  My posterkids for these are some
of the actions in a web-ified email archive or WebMail ap.  These would
include "next message in thread" or "this message in threaded index
view."  Waiting for standard terms for these is a losing play.  Standard
terms in new application domains (such as 'home' in the Web) will
emerge, but predicating

- the other is author interest.  If the author is not given the opportunity
to create a complete user experience, they won't create the semantic
underpinnings, either.  If we let authors nominate hotkeys, they will
identify the top hot-key-able targets in the page.  Else, not.  We need
them identified; we need the carrot to bring the authors to the table.
I believe that asking authors to create intent-based events without affording
them the means to nominate UI event triggers for them will create
a feature gathering dust on the shelf like the 'link' element in HTML.

So, there is sufficient reason to let the author propose something.

The flip side is also true: removing the author's ability to nominate
keys will not achieve the standard UI names that you would prefer.
That is a topic of balance-of-terror detente among the OS vendors.
JTC1 SC35 is trying to do that and like ISO HTML, it will be roundly
ignored in the real world. The place where we can have a reasonable
expectation of uptake in the commercial Web is at one remove from the
user experience, in naming the intent-based events.

CSS needs semantic info in the 'content rep' to key when to do what.
If the hotkey is specified in a CSS rule with a #id selector, then
the CSS is not style, it is holding content hidden from the AT
cruising the DOM through the access API.

You're lost in some theoretical world if you don't admit that web
developers *must* optimize the look and feel of their web aps to stay
in business.

We *must* preserve the adjustability of that look and feel.  But we
will simply fail if we try to do anything less than facilitating that
optimization by the content developers.

Sir, you're dealing with two working groups, here.

The latest draft XHTML 2.0 has been developed by the HTML WG.

The idea that the XForms language is "good enough" in terms of
assuring access is a matter that was consensus in the PF WG the
last time it came up for consensus.

The current draft was supposed to be a Last Call draft, that the
HTML WG considered 'done.'  It is not.  Not even the HTML WG
thinks that they have got every detail right in this draft.  So
bear with us, it is a work in progress.

Is the only way to strike a deal between author and user interest that will
fly in the massively distributed-authoring flow of information on the Web.
