Hi Mirja

Thank you for your comment. You are perfectly right, the wording "theses environments" is quite vague.

As pointed out in the introduction of the I-D the CMP profile addresses machine-to-machine use cases and focusses on maximum automation of certificate management of such machine end entities as well as further communication of the involved PKI management entities.
-----------------------------snip-----------------------------
2.  Introduction

   This document specifies PKI management operations supporting machine-
   to-machine and IoT use cases.  The focus lies on maximum automation
   and interoperable implementation of all involved PKI entities from
   end entities (EE) through an optional Local Registration Authority
   (LRA) and the RA up to the CA. [...]
-----------------------------snip-----------------------------

I am happy to change the proposed charter text accordingly to make it more clear. Would this wording be better?
-----------------------------snip-----------------------------
3. The Certificate Management Protocol (CMP) is specified in RFC 4210,
and it offers a vast range of certificate management options.  CMP is
currently being used in many different industrial environments, but it
needs to be tailored to the specific needs of such machine-to-machine 
scenarios and communication among PKI management entities.  The
LAMPS WG will develop a "lightweight" profile of CMP to more efficiently
support of these environments and better facilitate interoperable
implementation, while preserving cryptographic algorithm agility.  In
addition, necessary updates and clarifications to CMP will be specified
in a separate document.  This work will be coordinated with the LWIG WG.
