Hi Chris

1 - i only saw one test listed below so wasnt sure which two tests you were
referring to.

2 - you wrote:
Test 192 "don't label your submit buttons as 'submit'" could be required by:
Guideline 1.1, Level 1, Success Criteria 1:
For all non-text content that is functional, such as graphical links or
buttons, text alternatives identify the purpose or function of the non-text
content.

I don't follow your train of thought.  Having the alt text for a graphic
"submit" button say "submit" sounds like identifying its purpose and
function to me.    I think there might be plainer language that might be
used - so there might be better alt text.  But I don't see how this alt text
would fail.

I agree but both 2 tests could possibly be required by these success
criteria:

Guideline 1.1, Level 1, Success Criteria 4:
Non-text content that does not provide information, functionality, or
sensory experience is marked such that it can be ignored by assistive
technology.

Guideline 2.4, Level 2, Success Criteria 3:
Blocks of repeated material, such as navigation menus and document headers,
are marked up so that they can be bypassed by people who use assistive
technology or who navigate via keyboard or keyboard interface.

Guideline 3.1, Level 3, Success Criteria 2:
Section headings and link text are understandable when read by themselves as
a group (for example, in a screen reader's list of links or a table of
contents).

Test 192 "don't label your submit buttons as 'submit'" could be required by:
Guideline 1.1, Level 1, Success Criteria 1:
For all non-text content that is functional, such as graphical links or
buttons, text alternatives identify the purpose or function of the non-text
content.

Could we get a clarification from the WCAG group - are these 2 tests are
covered by the guidelines?

The test suite status page shows which tests have been accepted by the
group:
http://www.w3.org/WAI/GL/WCAG20/tests/checkstatus.html

So far, there are only 10 tests accepted by the group. There are about 200
tests proposed for the entire suite.

Thanks for your comments.

Cheers,
Chris
