Receive notification of a recoverable error.
This corresponds to the definition of "error" in section 1.2 of the W3C XML 1.0 Recommendation. For example, a validating parser would use this callback to report the violation of a validity constraint. The default behaviour is to take no action.
The SAX parser must continue to provide normal parsing events after invoking this method: it should still be possible for the application to process the document through to the end. If the application cannot do so, then the parser should report a fatal error even if the XML recommendation does not require it to do so.
Filters may use this method to report other, non-XML errors as well.
@param exception The error information encapsulated in aSAX parse exception.
@exception org.xml.sax.SAXException Any SAX exception, possiblywrapping another exception.
