Well, both attributes exist for accessibility, but each carries
different semantics.  Beyond that, I didn't mean to imply a
"relationship".

Indeed.  The current draft doesn't omit @alt in any examples except
where it's marked up as <figure><img><legend></figure>.

It's been suggested to only allow @alt to be omitted when <img> is a
child of <figure>.  I think that works just as well as my suggestion
for requiring @title.  It probably works better and in a more
backward/forward compatible way.

Indeed.  Both attributes can exist, and and a UA would be expected to
present both.  I never meant to imply any UA behavior other than the
example I gave.
