I don't know if there is consensus on that, or necessarily even  
consensus on what "a subset" means.

I proposed several possible subset relationships in the email that Art  
cited above. The thread died at that point, so I don't know if we have  
consensus that those are the relevant subset relations. I would  
appreciate a reply from you or Mark, and also from Anne, on whether  
those are appropriate subset relations.

Assuming that my proposed subset relations are agreed upon, I believe  
at least one of them still does not hold with the current UMP and CORS  
drafts, my relation (A).
