[SAH] Thanks for the input, Pawel. I agree that I'd rather not see any change 
applied retroactively. With respect to choice "b" above, the issue is that RFC 
3688 says this: "NOTE: in order for a URN of this type to be assigned, the item 
being registered MUST have been through the IETF consensus process.  Basically, 
this means that it must be documented in a RFC." Drafts aren't RFCs, so I doubt 
that a request to register a value in the IETF namespace with an I-D reference 
specification will be approved.
