+ * This class adds (de)serialization of compound properties to/from arrays.

+ * class:
+ *
+ * N: Section 6.2.2
+ * ADR: Section 6.3.1
+ * ORG: Section 6.6.4
+ * CATEGORIES: Section 6.7.1
+ *
+ * In order to use this correctly, you must call setParts and getParts to
+ * retrieve and modify dates respectively.
