Comment 1: unique link names?
Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2008Jan/0025.html
(Issue ID: 2403)
Original Comment:

WCAG1 (checkpoint 13.1) requires unique link names.
I remember reading somewhere that WCAG-WG now says WCAG2 does not need it.
But 3.2.4 Consistent Identification of UI components does need it, no?

In other words, if value of two HREF attributes are different, the linked
text for the two hyperlinks should not be the same. Right?

Response from Working Group:

Success Criteria 2.4.4 and 2.4.9 require that link purpose be
determinable. Success criterion 3.2.4 is about consistency. If they go
to different places this should be determinable per 2.4.4 and 2.4.9.

2.4.4 requires that it be determinable from the link text alone, or
from the link text together with its programmatically determined link

2.4.9 requires that the purpose of each link to be identified from
link text alone. (3.2.4 plus 2.4.9 would be the closest equivalent to
13.1 from WCAG 1.0.)

The only exception to these is where the purpose or result of using a
link is ambiguous to everyone whether they have a disability or not.

Comment 2: SC 1.4.5 unclear
Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2008Jan/0032.html
(Issue ID: 2410)
Original Comment:

I really could not understand  the significance of " When the accessibility
supported technologies being used can achieve the visual presentation," for
the SC 1.4.5 and believe the drafting of the entire SC and the list items in
the exceptions can be improved. I had to refer to the "Understanding" and
"How to" docs to grasp the intent of the SC. So here is an alternative draft
for 1.4.5 for your consideration:
 <draft starts>
Information should be conveyed by text and not via an image of the text
especially When the accessibility-supported technology in use is capable of
generating ( or can be configured to generate) various visual presentations.

Except where:
- The image of the text can be visually customized by the user to meet
viewing preferences;
- It is necessary to preserve a particular presentation of text for the
</draft ends>

Response from Working Group:

We were happy that you were able to determine the meaning from the
Understanding document and Quick Reference document. It was a
difficult provision to word.

Thanks for your suggestion, but it seems to be just as difficult to
understand and has some wording problems.  We will continue to look at
this one though to look for simpler wording during our implementation

Comment 3: Components do not have "sensory" characteristics but just
attributes or characteristics.
Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2008Jan/0048.html
(Issue ID: 2426)
Original Comment:

The adjective "sensory" for characteristics does not seem appropriate
with regard to components

Proposed Change:
Drop the word "sensory"

Response from Working Group:

The term 'sensory' is used to separate the characteristics that depend
on particular senses from other characteristics that might be used to
describe components (that can be perceived by different senses). As a
result, we cannot remove the word without unduly expanding the
coverage of the provision.
