Subordinates definition table (SDT)
A group definition table identifies subordinate classes contained
within this class. This in effect groups classes for easier reference.
Only classes that support containment and scoping
should have an SDT.

be subordinate to the current class; they will also be examined
when object instances are sought in the current class.
