13. Acknowledgements

   The current authors would like to acknowledge their debt to the late
   Dr. Jon Postel, whose general model of IANA registration procedures
   and specific contributions shaped the predecessors of this document
   [RFC2048].  We hope that the current version is one with which he
   would have agreed but, as it is impossible to verify that agreement,
   we have regretfully removed his name as a co-author.
