  22  * Data type definitions for all oic.sec.* types defined in the
  23  * OIC Security Specification.
  24  *
  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.
  32  *
  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).
  36  *
  37  * TODO reconcile against latest OIC Security Spec to ensure all fields correct.
