I agree with this suggestion of making @longdesc "obsolete but conforming".
I would pair it with a proposal of a new attribute that provides links to
longer content descriptions for more than just the <img> element.

In addition, I would like to see a rationale document for the @longdesc
extension spec that addresses the often-heard objections in a succinct
manner. In particular I'd like to see an explanation of how the different
browsers different in their implementation and interpretation of the value
of the @longdesc attribute (some versions of IE mapping it to a description
rather than a link) and how AT deal and fix this situation. I believe this
is crucial for people to understand - on top of the author misuse of
@longdesc, which is far less harmful.

This rationale document can be just in the wiki, since it's additional
information for the decision making rather than part of the actual

This option has previously received some support in the TF and HTMLWG:
