rel-tag and arbitrary content

I received some good feedback from delicious about why
rel-tag isn't being used.  One point that was made is that
rel-tag only describes the page it's on, not a particular
link or other external content...and unfortunately the wiki
doc echoes the concern

http://microform
ats.org/wiki/rel-tag
rel="tag" is NOT designed for "tagging"
arbitrary URLs or external
content. There is demand for a general decentralized syntax
for tagging
URLs external to the current page, but this is not meant for
that. See xFolk and hReview for ways to tag arbitrary URLs.

But if we go and read xFolk or hReview to discover the
"general decentralized syntax for tagging", we are
presented with rel-tag:

http://microform
ats.org/wiki/hreview
"tags:: Tags are represented using a list of keywords
or phrases (using the rel-tag microformat for each
individual keyword or phrase tag) that the reviewer
associates with the item."

I'd have said "rel-tag modifies the page it's on or the
nearest microformatted content parent that supports tags
(hReview, xFolk, hfeed, hentry), whichever comes
first".  The advantage being that verbiage like that
can be translated into parsing without too much thought.

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?

As I pointed out last time, this issue comes up every six
months. It is 
worth considering that you don't need microformats to
extract data from 
del.icio.us; it's available in purely semantic form as RSS.
Also: 
rel-tag doesn't capture the data delivered by del.icio.us in
the way 
that is being disucssed; the tags apply to the links from
del.icio.us, 
not to the page as a whole. ~D

That's not to say that the addition of microformats would
not add extra 
functionality - I don't know of an RSS reader that can do
what Operator 
does to, say, add contacts to my address book or events to
my calendar, 
for instance; or to look up tags on Flickr.
