Also agreed. Furthermore, looking forward to times when hypertext may
be more than just <a href></a>, people should get accustomed to
semantic use of all valid elements.

I see the trust/authority issue in that. Still, there should be a way
to indicate the reciprocal relationship from a cited resource. It's
something to consider.

The 'rev' attribute could be more clearly documented but that is not
an excuse to treat it like it's deprecated. The power of 'rev' is
begging to be exploited, not feared.
<link rel="Next" href="page2.html"> means "yonder document is the next
document in the sequence."
In cross-domain linking, <a rev="whatiam" href></a> gives the author
of the referring document the power to define his document's role in
the relationship. "The current document is a comment on the linked
document." "This is a rebuttal to that." "This is evidence to support

That works on the other end of the same vector--the pingback receiver.
The off-site comment author would use rev="comment" to describe his
own document. Maybe we don't need a "cite" value for rel/rev because
we have the cite element but we could make good use of some other
rel/rev values to map discussions across domains.
