From https://tools.ietf.org/html/rfc4512 it can be said that an object class inherits the sets of *allowed* and required attributes from its superclasses Therefore the top object class contains all possible attributes? OR

A subclasses cannot contain any attribute which is not included in it's superclass?

Thank you! There is no such IETF mailing list to question RFCs, so this appears to be the best place.
