rfc2277 compliance

[Hallvard B Furuseth <h.b.furuseth@usit.uio.no>]

rfc2277 (IETF Policy on Character Sets and Languages) says:

> 2.  Where to do internationalization
> (...)
>   Where protocol
>   elements look like text tokens, such as in many IETF application
>   layer protocols, protocols MUST specify which parts are protocol and
>   which are text. [WR 2.2.1.1]

Which means [Syntaxes] should specify which syntaxes contain text and
which ones do not.

> 4.2.  Requirement for language tagging
>
>   Protocols that transfer text MUST provide for carrying information
>   about the language of that text.

This implies that LDAP needs something like an Accept-Language extended
operation similar to the HTTP Accept-Language: header.  It would specify
which languages the client prefers for LDAPResult.diagnosticMessage and
text in unsolicited notifications.
