- * The {@code Validator} class is responsible for managing On-Demand Validation.
- * The {@code Unmarshaller} class is responsible for managing Unmarshal-Time
- * Validation during the unmarshal operations.  Although there is no formal

- * {@code Marshaller} may detect errors, which will be reported to the
- * {@code ValidationEventHandler} registered on it.

- * <blockquote>
- *   If the client application does not set an event handler on their
- *   {@code Validator}, {@code Unmarshaller}, or {@code Marshaller} prior to
- *   calling the validate, unmarshal, or marshal methods, then a default event 
- *   handler will receive notification of any errors or warnings encountered.  
- *   The default event handler will cause the current operation to halt after 
- *   encountering the first error or fatal error (but will attempt to continue 
- *   after receiving warnings).

- * <b>Handling Validation Events</b><br>
- * <blockquote>
- *   There are three ways to handle events encountered during the unmarshal,
- *   validate, and marshal operations:
- *    <dl>
- *        <dt>Use the default event handler</dt>
- *        <dd>The default event handler will be used if you do not specify one

- *        </dd>
- * 
- *        <dt>Implement and register a custom event handler</dt>
- *        <dd>Client applications that require sophisticated event processing
- *            can implement the {@code ValidationEventHandler} interface and
- *            register it with the {@code Unmarshaller} and/or
- *            {@code Validator}.
- *        </dd>
- *

- *            during the unmarshal, validate, and marshal operations and 
- *            returns them to the client application as a

- *
- * <p>
- * <b>Validation and Well-Formedness</b><br>
- * <blockquote>
- * <p>
- * Validation events are handled differently depending on how the client 
- * application is configured to process them as described in the previous
- * section.  However, there are certain cases where a Jakarta XML Binding Provider indicates
- * that it is no longer able to reliably detect and report errors.  In these
- * cases, the Jakarta XML Binding Provider will set the severity of the ValidationEvent to
- * FATAL_ERROR to indicate that the unmarshal, validate, or marshal operations 
- * should be terminated.  The default event handler and 
- * {@code ValidationEventCollector} utility class must terminate processing
- * after being notified of a fatal error.  Client applications that supply their 
- * own {@code ValidationEventHandler} should also terminate processing after
- * being notified of a fatal error.  If not, unexpected behaviour may occur.
- * </blockquote>
- *
- * <p>
- * <a id="supportedProps"></a>
- * <b>Supported Properties</b><br>
- * <blockquote>
- * <p>
- * There currently are not any properties required to be supported by all 
- * Jakarta XML Binding Providers on Validator.  However, some providers may support 
- * their own set of provider specific properties.
