  /**
   * The <code>Validate</code> annotation is used to mark a method in
   * a serializable object that requires a callback from the persister
   * once the deserialization completes. The validate method is invoked
   * by the <code>Persister</code> after all fields have been assigned
   * and before the commit method is invoked.
   * <p>
   * Typically the validate method is used to validate the fields that
   * have been assigned once deserialization has been completed. The
   * validate method must be a no argument public method or a method
   * that takes a <code>Map</code> as the only argument. When invoked 
   * the object can determine whether the fields are valid, if the  
   * field values do not conform to the objects requirements then the
   * method can throw an exception to terminate deserialization.
