I hope that PF will review Ian's proposal in order to help the HTML working group in assessing it. (Saying that we should look at <canvas> rather than solving @summary really doesn't help.) To perhaps kickstart a response: Our wikipage SummaryForTabe[1] identifies as primary problem the fact that Ian hasn't proposed a _programmatically-determined_ summary mechanism. The wiki points to WCAG 2.0 a definition of "programmatically-determined":[2] "Content that can be "programmatically determined" can be transformed (by user agents including AT) into different sensory formats (e.g., visual, auditory) or styles of presentation need by individual users. If existing assistive technologies cannot do this, then the information cannot be said to be programmatically determined." Simply put, this means that the table summary has to be semantically marked up as separate from the table caption. And since Ian's proposal only lumps everything into <caption> without separating between what is captioning content and what is summarizing content, his proposal falls through on this point. I think it would be quite beneficial to focus on this particular point to bring the debate forward.
