I'm suggesting we keep the tests at a fine level of granularity. For example
these tests for header element could all be rolled into one but that might
cause problems later. The test for H1 may change (perhaps we decide there
should only be one H1 in the doc) and then we would have to modify the group
test and create a new test for H1. If they are separate then it's easier to
modify only the parts that change. My computer programmer instincts tell me
to do it this way.

I agree. In the checklist or techniques documents they should be combined so
they are more human readable. If the user really wants to get down to the
nitty gritty they can look at the test cases. With these 3 different views
(techniques, checklists, test cases) the WCAG will be *very* clearly
defined. Well, at least for HTML.

I think we can do this now with our current materials. If we take text from
the techniques, checklist and test case then mix them together we get
something like:


Use the alt attribute of the img element to provide a text alternative for
images. (from techs)

Each image must have alt text that is not empty of filled with placeholder
text. (from checklist)

Check img element for the presence of an alt attribute. (from test case)

Compare the alt attribute value to the list of placeholder values (from test
