-- EXPORTS All 
-- The types and values defined in this module are exported for use in the other ASN.1
-- modules contained within the Directory Specifications, and for the use of other
-- applications which will use them to access Directory services. Other applications
-- may use them for their own purposes, but this will not constrain extensions and
-- modifications needed to maintain or improve the Directory service.
