JRG: The original purpose of this checkpoint was to support WCAG 1.0 requirement that when the ALT attribute is set explicitly to null (i.e. ALT=""), that nothing be rendered. This is to try to minimize the number of empty image placeholders on a page. I am concerned about having an open ended requirement to a checkpoint that was originally pretty narrow in scope and would be moved further away from the original intent with your proposed change.
