DIT changes approval

[sysadm+ldap-technical]

Hello,
Is there any way to approve (past or future) DIT changes by more than one 
people? OpeLDAP has ACL sets, I know. But I don't understand, how (or even can 
I) to use it forr approve changes in (part of) DIT by two or more people (must 
not singly, but whole set of people).
