There is also the implicit association given by the fact that the
caption immediately follows the image. Visually, one assumes that the
caption would be placed next to or beneath the image; nonvisually,
one would hear or read the caption directly after the image or its
alternate text. So there is certainly nothing "wrong," in practical
terms, with simply placing them together in a logical div and not
worrying further about it. (One also assumes that the text of the
caption should clearly relate to the image -- clear writing will help
make the association clear.)
For scripting purposes I have occasionally needed to tie an image and
its caption explicitly by giving them related IDs that a particular
javascript function can call (e.g. img id="img1" and p id="img-
caption"), and it would be helpful in these situations to have a
standard syntax for that explicit relation. But the availability of
such syntax should not imply that everyone needs to use it for all
markup, all the time; I can't see it being useful in ordinary web
design (to the reader/user, which should ultimately be the point)
unless there are actions associated with the image and caption.
