During October 7 teleconference, I took an action item to provide
examples of usability issues that are not covered in WCAG 2.0.
(discuss at Dublin F2F).

Ref: http://trace.wisc.edu/bugzilla_wcag/show_bug.cgi?id=1141

I think usability-related accessibility issues arise when users have
more cognitive load than they can process.  This happens, for example,
(1) when users with visual disability must memorize too many things to
operate a Web, or (2) when users with cognitive disabilities or
learning disabilities use a Web.

I enclose some examples I found so far.

(1) JIS X 8341-3 5.9.f) "Web content should be prepared not just with
text, but also with intelligible icons, illustrations, and audio
content." is the first example I would like to refer.

It has an informative reference that says "Additional information such
as intelligible icons, symbols, audio, etc. may be effective for
understanding and operation by those who have difficulty understanding
text content, such as those with learning difficulty. Figure 34 shows
an example of explanation using both text and illustration."

(2) Public comment from JIS: readable font
Readable font, mentioned in an editorial Note of "CSS Techniques: 8.1
Specifying fallback fonts", will be another example.

(3) Public comment from JIS: give pronunciation for difficult-to-read
Ref: http://trace.wisc.edu/bugzilla_wcag/show_bug.cgi?id=1159

(4) Public comment from JIS: use the correct character
