+/**
+ * <p>
+ *      Problem: Many Entities have dynamic properties as well as known properties.
+ *      Known properites can be binded explicitly with all dynamic properties need
+ *      to be captured also ensuring that there must not be any loss in information
+ *      during deserialization / serialization process.
+ * </p>
+ * <p>
+ *     This contract allows the deserialization mechanism to catch those dynamic properties
+ *     in a Map so that deserialization mechanism will not loose any information and
+ *     can be serialized back with no loss in dynamic properties information
+ * </p>
