+/*
+ * Reference RFC 6020.
+ *
+ * The union built-in type represents a value that corresponds to one of
+ * its member types.
+ *
+ * When the type is "union", the "type" statement (Section 7.4) MUST be
+ * present. It is used to repeatedly specify each member type of the
+ * union. It takes as an argument a string that is the name of a member
+ * type.
+ *
+ * A member type can be of any built-in or derived type, except it MUST
+ * NOT be one of the built-in types "empty" or "leafref".
+ *
+ * When a string representing a union data type is validated, the string
+ * is validated against each member type, in the order they are
+ * specified in the "type" statement, until a match is found.
+ *
+ * Any default value or "units" property defined in the member types is
+ * not inherited by the union type.
