Thanks, Chris.

Do we also have tests to determine (a) whether data tables have
<caption> elements and whether the content of the <caption> is identical
to the content of the summary attribute?

In my personal view, there's no need for the summary to have text
content if the <caption> is present and adequately describes the table
(as may often happen for small, simple data tables). And if <caption>
and summary are identical, people using screen readers hear the same
content twice.

Thanks.
John

In response to our test case review assignment, here are the tests
related 
to HTML table summaries:

Test 111 - All data table elements have a summary attribute.
http://www.w3.org/WAI/GL/WCAG20/tests/test111.html

Test 112 - All data table summaries contain text.
http://www.w3.org/WAI/GL/WCAG20/tests/test112.html

Test 113 - All data table summaries are greater than 10 printable 
characters.
http://www.w3.org/WAI/GL/WCAG20/tests/test113.html

Test 203 - All data table summaries describe the purpose and structure
of 
the table.
http://www.w3.org/WAI/GL/WCAG20/tests/test203.html

Test 114 - All layout tables have an empty summary or no summary.
http://www.w3.org/WAI/GL/WCAG20/tests/test114.html

There's been a lot of discussion regarding table summaries on the lists:
http://lists.w3.org/Archives/Public/w3c-wai-gl/2004AprJun/0806.html
http://lists.w3.org/Archives/Public/w3c-wai-gl/2003JulSep/0267.html
http://lists.w3.org/Archives/Public/w3c-wai-gl/2003AprJun/0213
http://lists.w3.org/Archives/Public/w3c-wai-ig/2005JanMar/0075
http://lists.w3.org/Archives/Public/w3c-wai-ig/2004OctDec/0346
http://lists.w3.org/Archives/Public/w3c-wai-ig/2004JulSep/0464.html
etc.

We currently don't have a test for long table summaries but I can add
one if 
people think it necessary.

I propose we take all these tests to a poll.

Cheers,
Chris
