That's the only reason why I think we should not let @aria-describedby replace @alt. >>>> Also, syntactically @aria-describedby has a larger syntax if the >>>> description is in an external document. >>> >>> In addition to require a much more verbose *markup*, there are also >>> "expected effect" differences.
