+1 to keep it out of revprop 0. I'd prefer to see the FS itself know about
the GUID, rather than the "repository". I think the GUID is going to be part
of the copy history, which we record in the FS. Maybe not now, but in the
future. Thus, the FS will know about GUIDs, so we should have the FS handle
the GUID itself (with the appropriate API to fetch it and regenerate it).

"part of the repository" can mean in the FS or in REPOS. That is part of the
problem here, so what seems obvious to you isn't as obvious to all :-)

Right. And the appropriate interfaces to deal with it.

For ra_dav, I think it would be good to make the GUID a live property on one
of the resources somewhere. The VCC comes to mind, as there is only one per
repository. Conceptually, I don't think it makes much sense there, but I
haven't thought thru it too much. But that is just about marshalling. The
larger question right now is "where to store the sucker"
