Note, however, that there is no requirement that 286N/A * the parser continue to report additional errors after a call to 286N/A * {@link #fatalError fatalError}. In other words, a SAX driver class 286N/A * may throw an exception after reporting any fatalError. 286N/A * Also parsers may throw appropriate exceptions for non-XML errors. 286N/A * For example, {@link XMLReader#parse XMLReader.parse()} would throw 286N/A * an IOException for errors accessing entities or the document.</p> 286N/A * @author David Megginson 286N/A * Receive notification of a warning. 286N/A * <p>SAX parsers will use this method to report conditions that 286N/A * are not errors or fatal errors as defined by the XML 286N/A * recommendation.
