1.  Introduction

1.1.  Overview

   A number of technologies and applications provide the ability for a
   person to choose a memorable, human-friendly name in a communications
   context, or to set such a name for another entity entity such as a
   device, account, contact, or website.  Such names are variously
   called "nicknames" (e.g., in chatroom applications), "display names"
   (e.g., in Internet mail), or "petnames" (see [1]); for consistency,
   these are all called "nicknames" in this document.

   Nicknames are commonly supported in technologies for textual
   chatrooms, e.g., Internet Relay Chat [RFC2811] and multi-party chat
   technologies based on the Extensible Messaging and Presence Protocol
   (XMPP) [RFC6120] [XEP-0045], the Message Session Relay Protocol
   (MSRP) [RFC4975] [I-D.ietf-simple-chat], and Centralized Conferencing
   (XCON) [RFC5239] [I-D.boulton-xcon-session-chat].  Recent chatroom
