Discovery of attribute type option support

[Jim Sermersheim <JIMSE@novell.com>]

Has there been any discussion on the issue of server advertisement of support for attribute type options? Specifically, I'm wondering if there are standard ways for an LDAP client to ask questions like:
"Does this server support language tags? If so, which attributes (or syntaxes) can I expect to use them with?"
"Does this server support the binary option? If so, which syntaxes can I use it with?"

I've seen some servers that include attributes with the binary option in their object class schema definitions, that doesn't seem right. And the inclusion of language tag information in the schema seems problematic.

I suppose the client can just try an operation, and if it fails, infer that it's not supported, but that's not very elegant.
