The key is that rel-tag is about the page or substantial part of the
page, while hreview makes the subject clear.  You can provide the
fullname/URI of the subject.

Also, your suggestion would require parsers to know about every
microformat container that supports tags.  That becomes a real challenge
for parsers to know about future microformats that may support tagging.

We've had discussions along these lines before.  At one point, someone
suggested adding a top level classname that would serve as a kind of
keyword flag to let parsers know how to apply the rel-tag.  However, we
never reached consensus on the need or the solution. (search for
scoping discussions)

Perhaps delicious' problems with rel-tag is a good enough concrete case
to renew discussion?
