I suppose TITLE could still be used to provide a short label for the image, independently of the longer description referred to by ALT, in cases where both a short label and a full description are warranted. The main problem with this proposal is that in processing the value of ALT, the user agent would have to determine whether it is a URI, then retrieve the associated resource if so, otherwise render the text of the attribute value. This would also leave the value of ALT syntactically unconstrained, whereas with a LONGDESC attribute, the syntax can be checked to ensure that it is a URI. Backward-compatibility with ua's that always render ALT would also serve as an argument against this proposal, though, in my view, not necessarily a fatal one.
