    abstract =  {Various Internet protocols define constructs for usernames, i.e., the local part of an address such as "localpart@example.com". This document describes a subset of characters to allow in usernames for maximal interoperability across Internet protocols. The subset might prove useful in cases where a provider offers multiple services using the same underlying identifier.},
