From HTML accessibility task force Wiki
Allowing @title and figure elements as fall back for @alt will, I think, cause some confusion, but this is something I "can live with" and is not worth raising an objection, especially since it is technically consistent with WCAG 2.0. In any, the thought, consideration, and work that has gone into the decision is quite evident. Thank you all!
I did not find any substantive accessibility related changes between the Working and Editors Draft.
Bug 13428 just on part on removing alt guidance
Figcaption is sometimes appropriate as fallback for @alt but always. Need to figure out the situations. See Examples of figure captions that may be inappropriately long for alt.
