> 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.

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): > * (2.4) Allow users the maximum time (infinite if possible) (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): > * (2.7) Use pull-down lists and check-boxes instead of text fields > for finite sets of possible values (such as states or provinces). 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. >Module: HTML Table Annotation > > This module adds the following requirement(s): > * (3.5) Use the summary attribute to describe the function and > contents of each table. > * (3.5) Use the abbr attribute to provide abbreviations for headers. 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): > * (1.1) Provide longdesc attributes for all images which are not > adequately described by the alt attribute. > > Exclusion Statement: "Some graphical content is undescribed and may be > inaccessible to users without the ability to display or view > graphics." Since we're improving in WCAG 1, I don't see why we can't propose using title first and longdesc only if necessary. >Module: Basic Audio > > Required by [89]Minimal Set > > This module adds the following requirement(s): > * (1.1) Provide transcripts for all non-streaming audio text > containing spoken words. 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 > > (1.1, 1.2) Provide text descriptions for all non-streaming audio > text containing spoken words. 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): > * (1.1, 1.2) Provide synchronized text streams and audio > descriptions for all streaming video. 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. >Module: Accessible PDF > > This module adds the following requirement(s): > * (4.1, 4.3) Create PDFs using the latest version of Adobe Acrobat, > and use the full accessibility features available. > * (1.1, 4.3) Provide a link or URL to the Adobe Access web site for > PDF to text conversion. > > Exclusion Statement: This site may contain PDF files which are > incompatible with assistive technology devices and software. 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. -- Joe Clark | joeclark@joeclark.org | <http://joeclark.org/access/> Accessibility articles, resources, and critiques || "I do not pretend to understand the mind of Joe Clark" -- Larry Goldberg
