Re: rfc2277 compliance

I should have stated that I'm not really concerned with how much we do
for RFC2277 compliance myself.  I just thought from the passwords/
SASLprep thread that at least you & Jim might be.  Anyway,

It's not clear to me if all syntaxes in [Syntaxes] except JPEG contain
text in the rfc2277 sense, or if just the ones matching the string
matching rules listed in [Syntaxes] 4.2 are text.

I know.  That's why I just mentioned elements that can not be associated
with language tags.

Check if that his entry has something like a preferredLanguage
attribute, you mean?  OK, but it doesn't help other users, or
unauthenticated users.

Fine by me.  (And I don't think it will be me who proposes it.)
