ISSUE-31
========

SUMMARY
There is no problem and the proposed remedy is to change nothing.

RATIONALE
There is no problem.

Another change proposal suggests removing all advice for authors writing 
alternative text, moving it to other documents. Historically, we have 
tried that (HTML4 had virtually no advice) and we have found it to be a 
poor solution: authors assume it is easy to write alternative text and 
thus do not attempt to learn anything about it. We need to try having such 
information as "in your face" as possible. Having additional documents 
would be additionally helpful, but does not preclude having detailed 
advice in the HTML spec itself.

A second change proposal suggests allowing otherwise non-conforming 
content to be conforming based on the presence of ARIA attributes. 
However, this is a layering violation and a language design error. ARIA is 
intended to only affect accessibility API mappings (and thus ATs). 
Features such as alt="", however, are relevant far beyond AT users, for 
example to text browsers. It would be wrong, therefore, to make solutions 
that exclusively affect accessibility APIs be a suitable alternative for 
solutions that are necessary for UAs that do not use accessibility APIs.

DETAILS
Change nothing.

IMPACT

POSITIVE EFFECTS
Having authoring advice will help advise authors.
Having conformance requirements independent of AT APIs will ensure that 
authors are encouraged to write documents that are optimal even for users 
that do not use ATs.

NEGATIVE EFFECTS
None.

CONFORMANCE CLASS CHANGES
None.

RISKS
None.
