/**
 * Encapsulate the location of a ValidationEvent.
 *
 * <p>
 * The <tt>ValidationEventLocator indicates where the ValidationEvent
 * </tt> occurred.  Different fields will be set depending on the type of
 * validation that was being performed when the error or warning was detected.
 * For example, on-demand validation would produce locators that contained
 * references to objects in the Java content tree while unmarshal-time
 * validation would produce locators containing information appropriate to the
 * source of the XML data (file, url, Node, etc).
