Tiré d'une liste IETF, un bon exemple de pourquoi c'est une mauvaise
idée :
From: Mark Crispin <mrc@Washington.EDU>
Sorting the addr-name opens a HUGE can of worms.
Given the names "Bandou Mitsugoro", "Mark Crispin", "Nishimura Aiko",
"Pedro Castro Gomez", and "Mao Zedong", a stupid sort will collate these
as:
Bandou Mitsugoro
Mao Zedong
Mark R. Crispin
Nishimura Aiko
Pedro Castro Gomez
and a falsely-clever sort will collate these as:
Nishimura Aiko
Mark R. Crispin
Pedro Castro Gomez
Bandou Mitsugoro
Mao Zedong
Both of these are totally wrong.
The actual correct collation, assuming(!) surname-first collation and
Latin character ordering(!!), is:
Bandou Mitsugoro
Pedro Castro Gomez
Mark R. Crispin
Mao Zedong
Nishimura Aiko
due to where the surname is located in various cultures.
And even that is making multiple unwarranted assumptions. The addr-name
may not even be a name that has a surname e.g., a corporate name. Latin
character ordering may not be correct either; in Japanese "Bandou" will
collate before "Nishimura", but "Tanaka" will collate before either of
these.
This is why this was punted to be a sort of the addr-mailbox. Once again,
changing this now would be an incompatible change that may benefit some,
will cost others, and will create instability and unreliability.
