IMHO, using empty
alt attributes to mark decorative images is a good approach, because that's exactly what DAISY recommends for
decorative images.
I'd recommend the following approach for images without
alt attributes:
- exclude them from the loi, but also add the image information to an error log
- add an alt="" attribute
- optional: add a role="presentation" attribute, but only in epub3 books
- display an error log listing all images without alt attributes
