I don't think that is what the AI54 proposal says. Under "Images of  
Pictures" (which includes photographs):

"Appropriate alt text value for a picture is a brief description, or  
name. As in all alt text authoring decisions, writing suitable text  
equivalents for pictures requires human judgment. The alt text value  
is subjective to the context where the image is used and the page  
author's writing style."

The example given is:
<figure>
<img src="1100670787_6a7c664aef.jpg" alt="My dog, Bubbles, digging in  
the sand on the beach">
<legend>Bubbles traveled everywhere with us.</legend>
</figure>

The AI54 proposal says non-empty alt is mandatory for any image that  
is not purely decorative.

Maciej
