No, to include a trackback link in an HTML document. All you need is
@rel for this case.

There is one, in Section Other link types:

Lacking semantics of their own, <div> and <span> are handy to when other
elements' semantics would conflict with whichever semantics you're
adding to things. For instance, prior to the introduction of <article>,
authors could have used <div> (as in <div class="article">) for marking
up articles.

So far as I've seen, the lack of a disambiguation mechanism isn't a
problem in practice. <div class="vcard"> means what it obviously means,
regardless of the presence or contents of head@profile.
