Implementation of SQL3 Structured Types with Inheritance and Value Substitutability

Summary: DB2 UDB implements SQL3 structured types with inheritance, enabling columns to store subtype values. Values are self-descriptive and manipulated only via system-generated accessors, with compile-time copy avoidance and inline-or-dynamic storage for performance.
