Maybe this phrase, which Steve also had, needs thinking: ]] and the value of the alt attribute and the content referenced by the longdesc attribute is the img element's fallback content [[ May be it is the longdesc *URL* that should be described as fallback, together with @alt? After all: we have several times made the point that the @longdesc text is optional, the user must *choose* to follow the longdesc link in order to get it. (This in contrast to aria-describedby/aria-labelledby and in contrast to @alt too. [And, for all I know, in contrast to the discussed aria-describedAT too.]) It is also congruent with how, for instance <video> may contain a link to a codec or direct download of the video in its fallback. Bringing in the phrase 'textual substitute' as description of @alt somewhere, would also be good (Vlad Alexander's proposal). Thus, for instance the following reformulation of the above quote: ]] and the value of the alt attribute is the img element's textual substitute which, together with the URL of the longdesc attribute, is the img element's fallback content [[ -- leif halvard silli
