So you think we can add semantic meaning by saying that if there is no ALT, then the image is "key content" = more important. We then get this semantic hierarchy: +1 = noalt (the highest value) 0 = alt="text" (neutral) -1 = alt="" lowest value The first audience for a this would be the authors. And we would not get it. Because the lowest value and the highest value would to us look almost the same. For us, this would require first of all a decision «do I need ALT at all?» Then, who would press that button just in order to add an empty alt=""? Who would answer yes, just to type alt=""? This would lead to a dramatic increase of IMG as «key content» (i.e. zero-alt). This said, I don't feel convinced that an extra attribute is what we need - that would just be one more decision to make, and more things that could go wrong. -- leif halvard silli
