Bug 37277 Title Area Dialog requires navigation to the error message
2.1 it is currently not possible to navigate to an error message. Sceen reader users need to use the JAWS cursor to find the error message and continue. We should 1) Make the label navigable 2) Make the label the next element in the tab order after the next button (we may get this for free).

 * of message it is.
 * <p>
 * The valid message types are one of <code>NONE</code>, 
 * <code>INFORMATION</code>, <code>WARNING</code>, or <code>ERROR</code>.
 * </p>
 * <p>
 * Note that for backward compatibility, a message of type <code>ERROR</code> 
 * is different than an error message (set using <code>setErrorMessage</code>). 
 * An error message overrides the current message until the error message is 
 * cleared. This method replaces the current message and does not affect the 
 * error message.
