No. To a parser, the above are *exactly* the same. The generate *the
same thing* in the DOM.

Right. So whether we call it <br/> or <empty/> is irrelevant.

An interesting assertion. I'd love to see what part of the spec led
you to believe _that_.

But the only differences between David's inline box model and the
spec's is that known errors, ambiguities, and deficiencies in the spec
have been cleared up. If you implement the spec's version, then
correct the obvious problems that immediately surface, then you end up
with David's version!
