We *do* have an hCard profile with URI, thanks to DanC:


But even without that, it is not unreasonable to assume that class="vcard"
is an hCard.

Just as it is not unreasonable (as in they all do it) for a browser to
assume that <html> is an HTML document even if there is no DOCTYPE that
points to a DTD URL which defines the element <html> as such.

We'll get to the point in a few years where more folks are using profiles,
but for now, microformats are like the early days of HTML where no one
bothered to use DTDs.  Be patient, we'll get there.
