I agre.

This is especially important since using *both* longdesc *and* a d-link
would create a very annoying redudndancy for people using screen
redaers-- just the sort of thing we're trying to discourage elsewhere.

Subject: [techs] d-link Test 9


In our recent straw poll, the group accepted the test for d-link:

test 9 - All IMG elements that have a LONGDESC attribute also have an
associated 'd-link'. http://www.w3.org/WAI/GL/WCAG20/tests/test9.html

However there were several people that voted for killing it and most
people voted that it be "optional". I thought we should have some
discussion on the list as a result of the close decision.

The "d-link" was a temporary measure to support image long descriptions
until there was user agent support for the LONGDESC attribute. We know
that d-link will eventually be not required so the question is - when?

Is there yet enough user agent support for LONGDESC that we should not
require d-link? How do we judge when there is enough support for
LONGDESC that we can dump d-link. Is there something we can do to
increase the support of LONGDESC so d-link can be quickly removed?

Note that d-link is currently a level 1 requirement because it maps to
guideline 1.1, Level 1, Success Criteria 2. I believe that it should be
a level 2 or level 3 requirement.

Comments appreciated.

Cheers,
Chris
