BlueGriffon has supported ARIA for a while. I don't think it is alone in supporting ARIA ... Doesn't Adobe Dreamweaver support, for example? Of course, authors could retype the alt value, manually. I predict this will not happen often ... I also predict that we will, generally, see aria-labelledby support before we see <picture> support (however, this perhaps counts as nothing more than a wild guess). >>>> <figure> >>>> <ficaption>Caption</figcaption> >>>> <picture> >>>> <source src=files > >>>> <img src=file > >>>> </picture> >>>> </figure> >>> >>> Your example has not @alt anywhere.

" OK. Then check the figure element example in the section "Graphical representation of some of the surrounding text". [1] Or try the validator.
