But the longdesc is not required to be IN the Web Unit. Just available from
it.  so it doesn't matter if Longdesc is considered part of the Web Unit or

1.1.1 in the case where the value of the ALT attribute alone doesn't provide
the same information as the image, but considered together with the
resourced which LONGDESC points to, the success criterion is satisfied.
Thus, if according to my example I make a conformance claim about a.html,
and b.html (to which LONGDESC refers) isn't part of the same Web unit, an
evaluator can't take it into account in assessing the conformance of a.html.
I would have to amend my conformance claim explicitly to include b.html.

I know this may seem pedantic, but that's how technical specifications are
applied, particularly when controversy arises.
