openldap.schema and core.schema questions

[Ron Wheeler <rwheeler@artifact-software.com>]

This may be a silly question but I am curious about why this class does 
not have 'top' (or some other class) as  its base class.

objectClass ( OpenLDAPobjectClass:6
   NAME 'OpenLDAPdisplayableObject'
   DESC 'OpenLDAP Displayable Object'
   MAY displayName AUXILIARY )

In core.schema, searchGuide is marked as obsolete and replaced by 
enhancedSearchGuide but enhanced searchGuide is never used and the 
obsolete searchGuide is used in 6 ObjectClasses. Is there a reason for this?
