22 * Data type definitions for all oic.sec.* types defined in the
23 * OIC Security Specification.
25 * Note that throughout, ptrs are used rather than arrays. There
26 * are two primary reasons for this:
27 * 1) The Spec defines many structures with optional fields, so pre-
28 * allocating these would be wasteful.
29 * 2) There are in many cases arrays of Strings or arrays of Structs,
30 * which could not be defined as variable length arrays (e.g. array[])
31 * without breaking from the structure order and definition in the Spec.
33 * The primary drawback to this decision is that marshalling functions
34 * will have to be written by hand to marshal these structures (e.g. to/from
35 * Persistent Storage, or across memory boundaries).
37 * TODO reconcile against latest OIC Security Spec to ensure all fields correct.
