Dear Jack Pickard ,

Thank you for your comments on the 2006 Last Call Working Draft of the
Web Content Accessibility Guidelines 2.0 (WCAG 2.0
http://www.w3.org/TR/2006/WD-WCAG20-20060427/). We appreciate the
interest that you have taken in these guidelines.

We apologize for the delay in getting back to you. We received many
constructive comments, and sometimes addressing one issue would cause
us to revise wording covered by an earlier issue. We therefore waited
until all comments had been addressed before responding to commenters.

This message contains the comments you submitted and the resolutions
to your comments. Each comment includes a link to the archived copy of
your original comment on
http://lists.w3.org/Archives/Public/public-comments-wcag20/, and may
also include links to the relevant changes in the updated WCAG 2.0
Public Working Draft at http://www.w3.org/TR/2007/WD-WCAG20-20070517/.

PLEASE REVIEW the decisions  for the following comments and reply to
us by 7 June at public-comments-WCAG20@w3.org to say whether you are
satisfied with the decision taken. Note that this list is publicly

We also welcome your comments on the rest of the updated WCAG 2.0
Public Working Draft by 29 June 2007. We have revised the guidelines
and the accompanying documents substantially. A detailed summary of
issues, revisions, and rationales for changes is at
http://www.w3.org/WAI/GL/2007/05/change-summary.html . Please see
http://www.w3.org/WAI/ for more information about the current review.

Thank you,

(Issue ID: LC-820)

Part of Item:
Comment Type: TE
Comment (including rationale for proposed change):

There is no requirement at any level for documents to be valid. I
understand the need to make things technologically neutral but these
are not mutually exclusive.
If there is no requirement for validity, what is to stop different
browsers adding new elements and supporting them? We\'ll have an
equivalent situation to the layer and ilayer elements as new browsers
will add new elements they like, irrespective of the specification. As
well as that, we\'ll see the return of previously deprecated elements
such as font. The WAI has advocated good development standards for a
long time. Now is not the time to change.

Proposed Change:

Add a new success criterion (probably a level 2 success criterion as
it is a strengthening of the level 1), requiring that web units or
authored components are produced according to the formal specification
for the technology used.

Response from Working Group:

The working group looked at this topic carefully over an extended
period of time and concluded that requiring strict adherence to all
aspects of specifications does not necessarily result in an increase
in accessibility. For example, it is possible to create invalid pages
that present no accessibility barriers. It is also possible in certain
situations to enhance accessibility through the use of markup that is
not part of the specification.

The working group must work within its charter and only include things
that directly affected accessibility. Some aspects of "use
technologies according to specification" and validity do relate to
accessibility. However, others do not. So requiring validity would
take us beyond our charter. We do recommend it though and it is our #1
technique listed for conforming to SC 4.1.1.
