> I am in favor of flagging a violation if alt is absent or is null on an img within a figure. Thoughts? I agree, we should definitely look into figure and come up with some guidelines around failures and sufficient techniques. For example, in most situations a caption is not the same as alternative -- although it could be. Some figures are not images, e.g. code examples, and others do contain images or represent images. A figure could also contain multiple images. Role of presentation could also be used on inner images and role="img" could be applied to figure to further clarify that a figure is indeed an image figure. Figures also don't necessarily need a figcaption -- but it's not clear if they always need a figcaption or accessible name? While best practice is to reference the figcaption as the accessible name -- is that required -- it seems like figcaption is already programmatically associated.

As a screen reader user, I am not in favor of doing away with the alt or even setting a null alt on the img because I do not realize that there is an actual image present; nor can I use image-navigation to quickly move to the image. Nor can I copy / save the image locally if I wished to. The examples within HTML5 specs do use an a non-empty alt for images within a figure which is perfectly fine by me. I am in favor of flagging a violation if alt is absent or is null on an img within a figure. Thoughts? Thanks very much, Sailesh Panchang
