Requesting individual schema elements

Is there a mechanism by which an ldap client can request for a specific
schema element (attributetype, objectclass etc) using the OID or the
textual name of the element.
If not,
1. Should this be done by the matched values extension.
http://sec.isi.salford.ac.uk/download/MatchedValues-06.txt. The draft
has expired quite sometime bac.
OR
2. Can we consider special casing the schema search for assertions like
attributetypes=<attrname or oid> to only return the matched value ?
The 2nd option seems preferable.

Thanks,
