FWIW, I second this request. Allowing "two possible margin collapsing
behaviors in the margin-collapse-clear case" seems rather odd (and
opens further questions: Is it equivalent to saying that the second
clearance calculation in 9.5.2 is optional?...)

I also agree with Anton that this issue (about clearance computation)
is distinct (related, but well distinct) from the original 203 issue,
that was about the definition of the 'hypothetical position' of an
element with 'clear', necessary to determine when clearance is
