Hi Leif, Thanks for checking this. > +1 Super! (Typo: You had 'discription' 2 places in the text.) Fixed. Thanks. > 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?

(This in contrast to > aria-describedby/aria-labelledby and in contrast to @alt too.

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 [[ That part of the spec text is somewhat dependent on the outcome of alt ISSUE-31 question two [1]. For the time being, I made a note to that effect in the sample spec text [2]. It can be adjusted after ISSUE-31 is decided. longdesc needs to be inserted but just how is affected by the spec text for alt.
