aoqi@0	44	* Object that coordinates the marshalling/unmarshalling.
aoqi@0	45	*
aoqi@0	46	* <p>
aoqi@0	47	* This class takes care of the logic that allows code to obtain
aoqi@0	48	* {@link UnmarshallingContext} and {@link XMLSerializer} instances
aoqi@0	49	* during the unmarshalling/marshalling.
aoqi@0	50	*
aoqi@0	51	* <p>
aoqi@0	52	* This is done by using a {@link ThreadLocal}. Therefore one unmarshalling/marshalling
aoqi@0	53	* episode has to be done from the beginning till end by the same thread.
aoqi@0	54	* (Note that the same {@link Coordinator} can be then used by a different thread
aoqi@0	55	* for an entirely different episode.)
aoqi@0	56	*
aoqi@0	57	* This class also maintains the user-configured instances of {@link XmlAdapter}s.
aoqi@0	58	*
aoqi@0	59	* <p>
aoqi@0	60	* This class implements {@link ErrorHandler} and propages erros to this object
aoqi@0	61	* as the {@link ValidationEventHandler}, which will be implemented in a derived class.
