>Also, some things (like attr type options) need more than just an OID in a list. We need to specify where they can be used (which attrs or syntaxes support them). Likely best to extend the attributeTypes and LDAPsyntaxes to include additional fields... like X-FEATURES ( 1.2.3 $ 2.3.4 ) where 1.2.3 might indicate language tags support and 2.3.4 might indicate binary transfer support.
