                  The Computerate Specifying Paradigm
             draft-petithuguenin-computerate-specifying-00

Abstract

   This document specifies a paradigm named Computerate Specifying,
   designed to simultaneously document and formally specify
   communication protocols.  This paradigm can be applied to any
   document produced by any Standard Developing Organization (SDO), but
   this document targets specifically documents produced by the IETF.
