+ * during the unmarshalling/marshalling.
+ *
+ *
+ * This is done by using a {@link ThreadLocal}. Therefore one unmarshalling/marshalling
+ * episode has to be done from the beginning till end by the same thread.
+ * (Note that the same {@link Coordinator} can be then used by a different thread
+ * for an entirely different episode.)
+ *
+ * This class also maintains the user-configured instances of {@link XmlAdapter}s.
+ *
+ *
+ * This class implements {@link ErrorHandler} and propages erros to this object
+ * as the {@link ValidationEventHandler}, which will be implemented in a derived class.
