Subtype Hierarchy Level Assignments

All four levels of this hierarchy are assigned to every subtype of every object type, including organizational objects, object definitions, and object instances. None of the hierarchy levels is defined as Mandatory for any subtype. The default classification value for all is set to Inherited.

For Domains, a subtype called Top-Level Domain has all its classification levels set to Explicit. A subtype called Child Domains has all its classification levels set to Inherited.

This is the most flexible design and the simplest to set up.
