There's no universal root-of-all-roots notion intended in the draft. All roots need not spring from the same place. However, as Steve noted, for any particular trust store there may be a set of trust anchors authorized to manage the contents of the trust store. To some extent, the set of TAs authorized to manage a trust store could be viewed as the roots-of-all-roots for that trust store.

In general, the idea is that there must be at least one trust anchor that is installed in any TA store for which trust is established using manual, out-of-band means. After this occurs, in- band management should be possible. Establishing a protocol to do this is the primary goal. Deciding on the trust anchor types to manage, extent of authorization to address, etc. is part of the scoping exercise.

Thank you Carl and Steve (I'm replying to Carl, but thanks go mostly to Steve) for helping me understand this. I now see that this is actually the *antithesis* of what I was erroneously thinking.

I think this is solves a problem that needs solving. I still want to see a way that we handle things other then X.509, and would like to see XML wrappers as well, because like XML or not, it's the way things are in much of the world.
