OK. I want(ed) a term covering both. I just took a look at a draft standard (not an IETF one, but uses several RFCs, so it's partly from that culture) and it uses the formulation "the message is invalid". -- Christopher Dearlove Senior Principal Engineer BAE Systems Applied Intelligence Laboratories __________________________________________________________________________ T: +44 3300 467500 | E: chris.dearlove@xxxxxxxxxxxxxx BAE Systems Applied Intelligence, Chelmsford Technology Park, Great Baddow, Chelmsford, Essex CM2 8HN. www.baesystems.com/ai BAE Systems Applied Intelligence Limited Registered in England & Wales No: 01337451 Registered Office: Surrey Research Park, Guildford, Surrey, GU2 7YP -----Original Message----- From: Joe Touch [mailto:touch@xxxxxxx] Sent: 26 June 2017 21:08 To: Dearlove, Christopher (UK); Petr Špaček; ietf@xxxxxxxx Subject: Re: I-D Action: draft-thomson-postel-was-wrong-01.txt ----------------------!

Wording could obviously have been better. I could see rejection being noisy, silent or somewhere in between. I was working off your term "reject" - which is IMO quite different from "ignore" (more than the difference between "explicitly" and "silently". Reject usually means some other action is taken, e.g., requiring an alert to the user, a change in the protocol state, or a response protocol message.
