> intended to be an illustrative straw man proposal to stimulate
I really think the term "straw man" is ill-advised for a number of
reasons, including basic meaning. A proposal like this is
self-evidently not a "straw-man argument."
"Discussion paper," anyone?

For "declaration," I guess we really mean "policy," yes?

This really needs to be much clearer.
Are we saying that an entity must post a policy stating what modules
it conforms to, but also do penance by listing all the ways in which
it lets the public down by failing to conform to *other* modules?
> This module adds the following requirement(s):

(unlimited if possible)
I still think nobody is saying what they really mean with this
requirement, which I've seen rewritten more ways than a Dear John
letter.
If WCAG really wants site authors never to use events with a
deadline, say so. It is clear to me that this is the intention.
>Module: Distinct Choices in Forms
>
> This module adds the following requirement(s):

This is not the best idea at all. Why should a screen-reader user
have to wait until the word Utah or Saskatchewan comes up when it is
so much easier to type UT or SK into a field?
Pull-down lists of this sort are convenient for the developer since
they preclude incorrect entries. They represent poor usability and
very poor usability for screen-reader users.

>
> This module adds the following requirement(s):

Abbreviations are not always necessary. In any event, existing WCAG
requirements state that accessible table markup should be limited to
*data* tables. As written, the requirement above also applies to
layout tables, and it shouldn't.
>Module: Extended HTML Tables
>
> This module adds the following requirement(s):
> * (4.3) Use the axis, colgroup, headers, etc. attributes on complex
> data tables.
You can't say "etc." Either the full range of attributes-- very
difficult to understand, hopelessly unwieldy to implement,
unsupported by virtually every authoring program, ignored by screen
readers-- is necessary or only bits and pieces are.
>Module: XML Natural Language
>
> This module adds the following requirement(s):
> * (1.4) Identify the primary natural language of the document using
> the xml;lang attribute.
Colon, not semicolon.
> This module adds the following requirement(s):
> * (1.1) Provide reasonable alt attributes for all images.
"Reasonable"? "Appropriate," I would say.
>Module: Image Descriptions
>
> Dependencies: Basic Images

> This module adds the following requirement(s):

Since we're improving in WCAG 1, I don't see why we can't propose
using title first and longdesc only if necessary.

What is "audio text"?
>Module: Basic Video
>
> Required by [90]Minimal Set
>
> This module adds the following requirement(s):
> * (1.1) Provide text descriptions of all non-streaming video.
Text descriptions *do not work* as a substitute for audio
description. This requirement must be removed.
>Module: Audio Captions
>
> Dependencies: Basic Audio, Synchronized Multimedia
>

There is no such thing as an audio caption, and a "text description"
is just as meaningless.
Here, yet bloody again, the WCAG politburo refuses to use the very
longstanding and *invariate* terminology in use for decades. Captions
are captions (whether closed or open); there is no such thing as an
audio caption. A "text description," whatever that is, certainly is
not a caption.
>Module: Streaming Multimedia
>
> Dependencies: Basic Audio, Basic Video, Synchronized Multimedia, Audio
> Descriptions
>
> This module adds the following requirement(s):

Just say "captions," not "text streams." The exact presentation
mechanism is outside the purview of these requirements. A "stream"
may not be necessary, as with open captioning.

> This module adds the following requirement(s):

I'm not sure there are many such PDFs given how PDF2txt and PDF2HTML
work. Multi-column text is, I suppose, the exception, but only with
some authoring programs.
