!! Confusion with [SystemAuxiliaryClass]
It appears that the [SystemAuxiliaryClass] can only be used at ObjectClass creation time and the [AuxiliaryClass attribute] can be used after creation, but we are unclear on this issue. Why is there what appears to be two attributes that are used for the same thing? 
* [AuxiliaryClass attribute]
* [SystemAuxiliaryClass]
