Module builder 

DynamicTypeBuilder + DynamicTypeBuilderFactory (XTypes 1.3 §7.5.4, §7.5.5).

Spec behavior:

• add_member validates name and id immediately against existing members (spec §7.5.4.1.2 preconditions).
• build() validates the final structure (inheritance cycle, mandatory discriminator, etc.) and returns an immutable DynamicType.
