[uf-discuss] rev'ing rel-directory

I'm afraid I've missed discussions around rel-directory , but was
prompted to take a look after stumbling over an OPML distributed
directories tutorial , wondering how best to do this using
OPML uses an attribute called "inclusion" to say that a remote
hierarchical dir is a sub dir of the local element. It's a neat idea,
essentially Gopher on top of HTTP+XML. But given the linking
capablitities of HTML, the OPML is redundant, as long as there is a
way of expressing "inclusion".
rel-directory would appear to be in the frame for an alternative based
on existing standards, only it's directed the opposite way :
indicates that the referenced resource is a directory which does or
should contain the current page
But HTML to the rescue, how about:
indicates that the current element is a directory element which
contains the referenced resource
Does that make sense?
The most obvious application of this would be in XOXO documents, along
the lines of the distributed dir idea.
A potentially cool demo application might be to transclude  any
remote page, stripped down to hierarchy+ labelled links. If this was
done to one level of transclusion, and the links in the remote page
rewritten to something like
http://mydir.org/tree?remote=http://thatpage.com/stuff so they could
be fed through the tree-browser, the demo could reveal the current web
as a "World Outline". Anyone got a bit of Ajax time on their hands?
