Appendix A

Required Entity Set

The Entity and Multiplicity columns are normative: §14.8 requires every Entity below, at the multiplicity stated, and §16.2 checks that each is bound in the Path Map. The Clause column is a non-normative index to the clauses that impose each Entity. The binding of each Entity to a concrete location and serialization format is declared by the Project's Path Map (§14.8).
