I now see that I overlooked that you actually stated that you - for some reason - modified the WAI-ARIA example - my emphasis: ]] As an example, in the WAI-ARIA 1.0 specification, there is an image listing _that_I_modified_, below: [[ > <div role="img" aria-labelledby="caption"> > <img src="example.png" alt="Some descriptive text"> > <p id="caption">A visible text caption labeling the image.</p> > </div> > > Which I believed to be equivalent to figure and figcaption. It should be damn close. Including the way that you designate the role of the <div> container to be role="img". The only thing I don't grok, is why you found it necessary to a) add content to @alt and b) remove role="presentation" - I don't see that this increases the similarity. > I don't believe I referenced role="presentation".

If you think so, then you should also take it up in context of WAI-ARIA. I, for one, find myself finding WAI-ARIA completely rational. I must say that I really have trouble seeing how the following can by any more controversial ... <figure role="img"> <img src="example.png" role="presentation" alt=""> <summary>A visible text caption labeling the image.</summary> </figure> .... than this (WAI-ARIA's example): <div role="img" aria-labelledby="caption"> <img src="example.png" role="presentation" alt=""> <p id="caption">A visible text caption labeling the image.</p> </div> -- leif halvard silli
