6.5.  Modifying the Session

   Offers and answers inside an existing session follow the rules for
   initial session negotiation.  Such an offer MAY propose a change in
   the number of RIDs in use.  To avoid race conditions with media, any
   RIDs with proposed changes SHOULD use a new ID, rather than re-using
   one from the previous offer/answer exchange.  RIDs without proposed
   changes SHOULD re-use the ID from the previous exchange.

I interpret this as saying (indirectly) that rids can't be renamed, you can only propose new ones.
