SimplePolicyCondition

The simplePolicyCondition contains an aggregation of PolicyVariable and PolicyValue.
I am trying to put this in LDAP schema and unable create an object of SimplePolicyObject.

objectclass ( 1.3.6.1.4.1.412.100.2.1.3.1.61 NAME 'PolicyVariableAux'
 SUP PolicyVariable AUXILIARY
 )

objectclass ( 1.3.6.1.4.1.412.100.2.1.3.1.62 NAME 'PolicyValueAux'
 SUP PolicyValue AUXILIARY
 )

objectclass ( 1.3.6.1.4.1.412.100.2.1.3.1.510 NAME 'SimplePolicyCondition'
 DESC 'Aux classes that can attach to
 dlm1SupportAccessInstance.'
 AUX ( PolicyVariableAux $ PolicyValueAux ) 
 )

Can anyone suggest the proper class hierarchy ? 

Thanx
Regards
