ohair@286 46 * <p>
ohair@286 47 * This class takes care of the logic that allows code to obtain
ohair@286 48 * {@link UnmarshallingContext} and {@link XMLSerializer} instances
ohair@286 49 * during the unmarshalling/marshalling.
ohair@286 50 *
ohair@286 51 * <p>
ohair@286 52 * This is done by using a {@link ThreadLocal}. Therefore one unmarshalling/marshalling
ohair@286 53 * episode has to be done from the beginning till end by the same thread.
ohair@286 54 * (Note that the same {@link Coordinator} can be then used by a different thread
ohair@286 55 * for an entirely different episode.)
ohair@286 56 *
ohair@286 57 * This class also maintains the user-configured instances of {@link XmlAdapter}s.
ohair@286 58 *
ohair@286 59 * <p>
ohair@286 60 * This class implements {@link ErrorHandler} and propages erros to this object
ohair@286 61 * as the {@link ValidationEventHandler}, which will be implemented in a derived class.
