   IANA is asked to registers three URIs in the IETF XML registry:
   URI: urn:ietf:params:xml:ns:yang:softwire-ce, 
   URI: urn:ietf:params:xml:ns:yang:softwire-br, 
   URI: urn:ietf:params:xml:ns:yang:softwire-common
  IANA is requested to registers three YANG modules in the YANG Module Names
  registry:ietf-softwire-ce, ietf-softwire-br, ietf-softwire-common.

  All the necessary information is in the IANA considerations document. It is
  clear enough that the IANA will be able to implement it.
