Okay. I'll remove it now from the proposal. Your explanation makes sense. aria-labelled was not part of the WAI CG recommendation either. Janina had asked me to add aria-labelled to the proposal back in April [2], which I did on provision that no one objected to it [1]. > will get back to you on role="presentation". That would be great. Thank you.
