DISCUSS:
----------------------------------------------------------------------

RFC 3326 doesn't specify what the receiver will do if two reason values have
the same protocol value. Are we reasonably sure that existing implementations
of SIP won't throw an error if they get this, or does there need to be some
sort of negotiation mechanism?
