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 such as a device,
   account, contact, or website.  Such names are variously called
   "nicknames" (e.g., in chat room applications), "display names" (e.g.,
   in Internet mail), or "petnames" (see [PETNAME-SYSTEMS]); for
   consistency, these are all called "nicknames" in this document.

   Nicknames are commonly supported in technologies for textual chat
   rooms, 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] [RFC7701], and Centralized Conferencing (XCON)
   [RFC5239] [XCON-SYSTEM].  Recent chat room technologies also allow
