 * <p>
 * The <tt>Marshaller</tt> class is responsible for governing the process
 * of serializing Java content trees back into XML data.  It provides the basic
 * marshalling methods:
 *
 * <p>
 * <i>Assume the following setup code for all following code fragments:</i>
 * <blockquote>
 *    <pre>
 *       JAXBContext jc = JAXBContext.newInstance( "com.acme.foo" );
 *       Unmarshaller u = jc.createUnmarshaller();

 *       Marshaller m = jc.createMarshaller();
 *    </pre>
 * </blockquote>
 * 
 * <p>
 * Marshalling to a File:
 * <blockquote>
 *    <pre>
 *       OutputStream os = new FileOutputStream( "nosferatu.xml" );
 *       m.marshal( element, os );
 *    </pre>
 * </blockquote>
 *
 * <p>
 * Marshalling to a SAX ContentHandler:

 *    <pre>
 *       // assume MyContentHandler instanceof ContentHandler
 *       m.marshal( element, new MyContentHandler() );  
 *    </pre>
 * </blockquote>

 *
 *       m.marshal( element, doc );
 *    </pre>
 * </blockquote>
 *
 * <p>
 * Marshalling to a java.io.OutputStream:
 * <blockquote>
 *    <pre>
 *       m.marshal( element, System.out );
 *    </pre>
 * </blockquote>
 *
 * <p>
 * Marshalling to a java.io.Writer:

 *    </pre>
 * </blockquote>
 *
 * <p>
 * Marshalling to a javax.xml.transform.SAXResult:
 * <blockquote>
 *    <pre>
 *       // assume MyContentHandler instanceof ContentHandler
 *       SAXResult result = new SAXResult( new MyContentHandler() );
 *
 *       m.marshal( element, result );

 * <b>Marshalling content tree rooted by a JAXB element</b><br>
 * <blockquote>
 * The first parameter of the overloaded 
 * <tt>Marshaller.marshal(java.lang.Object, ...)</tt> methods must be a 
 * JAXB element as computed by 
 * {@link JAXBIntrospector#isElement(java.lang.Object)}; 
 * otherwise, a <tt>Marshaller.marshal</tt> method must throw a 
 * {@link MarshalException}. There exist two mechanisms 
 * to enable marshalling an instance that is not a JAXB element.
 * One method is to wrap the instance as a value of a {@link JAXBElement}, 
 * and pass the wrapper element as the first parameter to 
 * a <tt>Marshaller.marshal</tt> method. For java to schema binding, it 
 * is also possible to simply annotate the instance's class with 
 * &#64;{@link XmlRootElement}.
 * </blockquote>
 *
 * <p>
 * <b>Encoding</b><br>
 * <blockquote>
 * By default, the Marshaller will use UTF-8 encoding when generating XML data
 * to a <tt>java.io.OutputStream</tt>, or a <tt>java.io.Writer</tt>.  Use the 
 * {@link #setProperty(String,Object) setProperty} API to change the output 
 * encoding used during these marshal operations.  Client applications are
 * expected to supply a valid character encoding name as defined in the
 * <a href="http://www.w3.org/TR/2000/REC-xml-20001006#charencoding">W3C XML 1.0
 * Recommendation</a> and supported by your Java Platform.
 * </blockquote>
 * 
 * <p>
 * <b>Validation and Well-Formedness</b><br>
 * <blockquote>
 * <p>
 * Client applications are not required to validate the Java content tree prior
 * to calling any of the marshal API's.  Furthermore, there is no requirement 
 * that the Java content tree be valid with respect to its original schema in
 * order to marshal it back into XML data.  Different JAXB Providers will 
 * support marshalling invalid Java content trees at varying levels, however
 * all JAXB Providers must be able to marshal a valid content tree back to 
 * XML data.  A JAXB Provider must throw a <tt>MarshalException</tt> when it
 * is unable to complete the marshal operation due to invalid content.  Some
 * JAXB Providers will fully allow marshalling invalid content, others will fail
 * on the first validation error.
 * <p>
 * Even when schema validation is not explictly enabled for the marshal operation,
 * it is possible that certain types of validation events will be detected 
 * during the operation.  Validation events will be reported to the registered
 * event handler.  If the client application has not registered an event handler
 * prior to invoking one of the marshal API's, then events will be delivered to
 * a default event handler which will terminate the marshal operation after
 * encountering the first error or fatal error. Note that for JAXB 2.0 and
 * later versions, {@link javax.xml.bind.helpers.DefaultValidationEventHandler} is
 * no longer used.
 * 
 * </blockquote>
 *
 * <p>
 * <a name="supportedProps"></a>
 * <b>Supported Properties</b><br>
 * <blockquote>
 * <p>
 * All JAXB Providers are required to support the following set of properties.
 * Some providers may support additional properties.
 * <dl>
 *   <dt><tt>jaxb.encoding</tt> - value must be a java.lang.String</dt>
 *   <dd>The output encoding to use when marshalling the XML data.  The
 * 		 Marshaller will use "UTF-8" by default if this property is not
 *  	 specified.</dd>
 *   <dt><tt>jaxb.formatted.output</tt> - value must be a java.lang.Boolean</dt>
 *   <dd>This property controls whether or not the Marshaller will format
 * 	 the resulting XML data with line breaks and indentation.  A
 *       true value for this property indicates human readable indented 
 *       xml data, while a false value indicates unformatted xml data.
 *       The Marshaller will default to false (unformatted) if this 
 *       property is not specified.</dd>
 *   <dt><tt>jaxb.schemaLocation</tt> - value must be a java.lang.String</dt>
 *   <dd>This property allows the client application to specify an
 *       xsi:schemaLocation attribute in the generated XML data.  The format of 
 *       the schemaLocation attribute value is discussed in an easy to 
 *       understand, non-normative form in 
 *       <a href="http://www.w3.org/TR/xmlschema-0/#schemaLocation">Section 5.6 
 *       of the W3C XML Schema Part 0: Primer</a> and specified in 
 *       <a href="http://www.w3.org/TR/xmlschema-1/#Instance_Document_Constructions">
 *       Section 2.6 of the W3C XML Schema Part 1: Structures</a>.</dd>
 *   <dt><tt>jaxb.noNamespaceSchemaLocation</tt> - value must be a java.lang.String</dt>
 *   <dd>This property allows the client application to specify an
 *       xsi:noNamespaceSchemaLocation attribute in the generated XML 
 *       data.  The format of the schemaLocation attribute value is discussed in 
 *       an easy to understand, non-normative form in 
 *       <a href="http://www.w3.org/TR/xmlschema-0/#schemaLocation">Section 5.6 
 *       of the W3C XML Schema Part 0: Primer</a> and specified in 
 *       <a href="http://www.w3.org/TR/xmlschema-1/#Instance_Document_Constructions">
 *       Section 2.6 of the W3C XML Schema Part 1: Structures</a>.</dd>
 *   <dt><tt>jaxb.fragment</tt> - value must be a java.lang.Boolean</dt>
 *   <dd>This property determines whether or not document level events will be
 *       generated by the Marshaller.  If the property is not specified, the 
 *       default is <tt>false</tt>. This property has different implications depending
 *       on which marshal api you are using - when this property is set to true:<br>
 *       <ul>
 *         <li>{@link #marshal(Object,org.xml.sax.ContentHandler) marshal(Object,ContentHandler)} - the Marshaller won't
 *             invoke {@link org.xml.sax.ContentHandler#startDocument()} and
 *             {@link org.xml.sax.ContentHandler#endDocument()}.</li>
 *         <li>{@link #marshal(Object,org.w3c.dom.Node) marshal(Object,Node)} - the property has no effect on this
 *             API.</li>
 *         <li>{@link #marshal(Object,java.io.OutputStream) marshal(Object,OutputStream)} - the Marshaller won't
 *             generate an xml declaration.</li>
 *         <li>{@link #marshal(Object,java.io.Writer) marshal(Object,Writer)} - the Marshaller won't
 *             generate an xml declaration.</li>
 *         <li>{@link #marshal(Object,javax.xml.transform.Result) marshal(Object,Result)} - depends on the kind of
 *             Result object, see semantics for Node, ContentHandler, and Stream APIs</li>
 *         <li>{@link #marshal(Object,javax.xml.stream.XMLEventWriter) marshal(Object,XMLEventWriter)} - the
 *             Marshaller will not generate {@link javax.xml.stream.events.XMLEvent#START_DOCUMENT} and
 *             {@link javax.xml.stream.events.XMLEvent#END_DOCUMENT} events.</li>
 *         <li>{@link #marshal(Object,javax.xml.stream.XMLStreamWriter) marshal(Object,XMLStreamWriter)} - the
 *             Marshaller will not generate {@link javax.xml.stream.events.XMLEvent#START_DOCUMENT} and
 *             {@link javax.xml.stream.events.XMLEvent#END_DOCUMENT} events.</li>
 *       </ul>
 *   </dd>
 * </dl>
 * </blockquote>
 * 
 * <p>
 * <a name="marshalEventCallback"></a>
 * <b>Marshal Event Callbacks</b><br>
 * <blockquote>
 * "The {@link Marshaller} provides two styles of callback mechanisms
 * that allow application specific processing during key points in the
 * unmarshalling process.  In 'class defined' event callbacks, application
 * specific code placed in JAXB mapped classes is triggered during
 * marshalling.  'External listeners' allow for centralized processing
 * of marshal events in one callback method rather than by type event callbacks.
 *
 * <p>
 * Class defined event callback methods allow any JAXB mapped class to specify 
 * its own specific callback methods by defining methods with the following method signatures:
 * <blockquote>
 * <pre>
 *   // Invoked by Marshaller after it has created an instance of this object.
 *   boolean beforeMarshal(Marshaller);
 * 
 *   // Invoked by Marshaller after it has marshalled all properties of this object.
 *   void afterMarshal(Marshaller);
 * </pre>
 * </blockquote>
 * The class defined event callback methods should be used when the callback method requires
 * access to non-public methods and/or fields of the class. 
 * <p>
 * The external listener callback mechanism enables the registration of a {@link Listener} 
 * instance with a {@link Marshaller#setListener(Listener)}. The external listener receives all callback events, 
 * allowing for more centralized processing than per class defined callback methods.
 * <p>
 * The 'class defined' and external listener event callback methods are independent of each other,
 * both can be called for one event. The invocation ordering when both listener callback methods exist is
 * defined in {@link Listener#beforeMarshal(Object)} and {@link Listener#afterMarshal(Object)}.
 * <p>
 * An event callback method throwing an exception terminates the current marshal process.
