             A Taxonomy on Private Use Fields in Protocols
                    draft-lonvick-private-tax-13.txt

Abstract

   This document attempts to provide some clarification for the way that
   private use fields have been used in protocols developed in the IETF.
   It is strictly a taxonomy of what has been published and offers no
   advice about how to design or use private use options.
