Re: H1 to H4 titles sub titles....

My difficulty with full use of comparable in a technical testing context
is that it can mean so many things to so many people.

While I can concur that by using headings someone using some AT products
can navigate on that basis, the question is, is that a function of the
page, or a presentation style. I don't believe most site developers
would connect their use of heading styles to navigation, but would
understand the visual appeal. This would be an item which can be
considered a potential testable step for 1194.31(a), as you cite, if
header navigation is considered part of the actual page navigation in
general. I don't believe headers are required for skipping repetitive
navigation or content, but might be accepted as one success technique
for that.

If you throw five IT accessibility people one a single page you get ten
accessibility answers! <smile>.

Excellent evaluation discussion.

Right, the technical standards do not require headings.
When S508 was written, browsers and AT did not support heading
navigation. But this has changed since.
The objective of the law is to provide "comparable access" to PWD.
Now 1194.31 (A) says "At least one mode of operation and information
retrieval that does not require user vision shall be provided, or
support for assistive technology used by people who are blind or
visually impaired shall be provided".
When the page uses text / image-text styled as headers, marking them
up with h-tags will allow comparable access to headers without
requiring blind users to read complete page using an info retrieval
feature supported by AT today that was not available in 2000-01. This
is a functional outcome.

The Access Board guide says "...a recognition that future technologies
may be developed, or existing technologies could be used in a
particular way, that could provide the same functional access in ways
not envisioned by these standards. In
evaluating whether a technology results in "substantially equivalent
or greater access," it is the functional outcome, not the form, which
is important".
I think the spirit and intent of the law are guiding factors- really
important during implementing any law.
So heading markup is required only when the page uses text /
image-text styled as headers.
