Description Carolyn MacLeod CLA 2017-12-04 14:16:58 EST 
Image alt text is allowed to be set to the empty string, i.e.
   <img src="only-for-show.png" alt=""></img>

alt="" tells accessible technology like screen readers that the image is purely for presentation, so ignore it.

So alt="" should not flag a validation error.
The value must be a string.
