In that regard: The ARIA tables says that <area> has role="link". But <area> is, nevertheless, *not* listed amongst the interactive elements. Why is that? An element with link role that isn't an interactive element sounds odd. We can put it like this: When object/img is an image map, is it then the <area> element that carries the link role(s)? or is it object/img? Or is it none of them - perhaps it is the particular area of the image which the <area> element designates that carries the link role(s)? We can also put it like this: can an image that acts as an image map - the img@usemap - be considered presentational? Note that when e.g. the anchor element is given the role="presentation", then - to ARIA supporting AT -it stops acting as a link. Thus, one should therefore assume that if we have <img role=presentation usemap=#m >, then the image stops acting as an image map. (Meaning what? That the area links stop working in the AT??? Or would AT handle the <area> elements regardless?) In that regard, since alt="<empty>" causes the role to be set to presentation, then this would make the image map stop working/be ignored, for AT. Meaning that if there are no parallell anhor links, the AT would not get any links. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
