Indeed. If the issue were that simple, I'd be all for this guideline.
(By the way, alt="" may be a convention, and a well-documented one, but it
is not in the HTML spec. The case of PDF artifacts is much better.)
Anyway:
What if my non-text content is in, say, an <object> element?
What if I bring it into existence via CSS, as with :hover:after? I can use
any URL (actually "URI") I want in that case, according to the spec. I
could cause a little JPEG of a flower to appear next to hovered links. How
do I mark that as skippable?
