As I've been pondering these issues, I've realized we can't guarantee that a user identifier can be (or include) someone's name. Although that might be a desirable property, a username is, after all, an account identifier. There is long precedent (e.g., in email) for allowing a smaller subset of characters in account identifiers than in display names. Thus I suggest that we add a paragraph like the following to 7613bis: A "username" or "user identifier" is a string of characters designating an account on a computing device or system, often but not necessarily for use by a person. Although some devices and system might allow a username to be part or all of a person's name, and a person might want their account designator to be part or all of their name, because of the complexities involved that outcome is not guaranteed for all human names on all computing devices or systems that follow the rules defined in this specification. Protocol designers and application developers who wish to allow a wider range of characters are encouraged to consider a separation between more restrictive account identifiers and more expressive display names.
