+ * A DynamicEObjectImpl which implements Serializable. This is required by Hibernate.

+ * TODO: probably serialization code has to be added to actually support serialization of a 
+ * DynamicEObjectImpl. Often however Hibernate won't really serialize the object, so it might not be
+ * necessary for most cases.
+ * 
+ * Implements Map so that Hibernate can use the MapAccessor to get to the values.
