We have tried to prevent misuse for example by including the protocol safeguards described in 4.1 Scope of Marking, the need for authorization in 7.1, and the user control described in 8.6. If an attacker injects marking, this should be removed by the network, or ignored by non-supporting entities. Also the user will see that troubleshooting/testing is happening.

Revised the final paragraph Section 1 Introduction as follows as per the comment.



   This document defines a new header field parameter "logme" for the

   "Session-ID" header field [RFC7989].  Implementations of this

   document MUST implement [RFC7989].
