Encapsulate the location of a ValidationEvent.
 The ValidationEventLocator indicates where the ValidationEvent 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).
