RE: interoperability of ;binary
Kurt,
I must once again object to using "string encoding" to refer to a binary
(BER) blob.
The reason for ;binary is probably to warn clients not to print the
contents. String encoding would, I believe, be an encouragement to print.
But, comparing the mess with jpegPhoto, simply leaving ;binary off
userCertifcate would not seem so bad.
Ron.

Yes. Some might be BER/DER string encodings as was done
in LDAPv2 for userCertificates (RFC2559).

Making a distinction in RFC2251bis scares me. One has to
go down the path of whether there multiple kinds of subtyping
and non-subtyping options. That is direct vs non-direct
subtyping options. Or, transfer options which act like
subtyping options in some contexts but not in others. We
end up having to redesign the feature, hence the protocol.
It's a slippery slope that I rather not step down into.
However, I am also quite willing to consider other options...
I'll even offer another one myself:
Replace:
An AttributeDescription with one or more options is
treated as a subtype of the attribute type without
any options.
with:
The relationship between an AttributeDescription with
one or more options with an AttributeDescription with
the same or related attribute type and a subset of the
same options is not defined in general. Such semantics
are defined on an option by option basis.
and update ;binary (and ;lang-*) as approrpiate.
Another approach would be to do both. That is, make the
replacement, remove ;binary to a separate document (an
extension). This would keep the "redesign" out of LDAPbis.
