2.  Introduction

   While using CMP [RFC4210] in industrial and IoT environments and
   developing the Lightweight CMP Profile
   [I-D.brockhaus-lamps-lightweight-cmp-profile] some limitations were
   identified in the original CMP specification.  This document updates
   RFC 4210 [RFC4210] to overcome these limitations.
