Note also that the WHATWG rel registry hasn't really been actively 
maintained yet, because the spec hasn't until recently been at all stable, 
and since becoming more stable the maintenance of the registry has been 
put on hald waiting to see what happens with the rel registry issue. If
we begin active maintenance I would expect it to quickly converge with the 
Microformats wiki page.

That would be fine by me too. We would need to add the two flags (how the 
relations affect <link> and <a>/<area>) to fully address the needs of the 
spec, but that is presumably fine.

My ideal would be something more like what Lachlan suggested, probably 
supported by a wiki for documentation purposes.

Any spec should probably be fine, not just RFCs. In particular, for 
instance, the "pingback" relation has had an old and stable spec for 
years (it even has multiple translations); I see no benefit to recasting 
that as an RFC or in fact changing it in any way -- we should just 
reference the existing spec and be done with it.
