I'm not sure either, but I think that the implication may be 
implicit.  When an RFC is superseded, a new RFC with a different RFC number 
is issued, but (if it's a full standard) the same STD number.

On balance, I'd say put the extra words in.  I don't think they'll cause 
any problems, and if they do I suppose we can always take them out again.

Generally, not, I think.  I think one could issue a new registration that 
supersedes a previous one and refers to an updated specification.  There's 
no explicit version in a MIME content-type.  It would be theoretically 
possible to define a version parameter if that was important, but I guess 
it would be viewed with some suspicion.
