XML PARSE exceptions
When an exception event occurs, the XML parser sets special register XML-CODE to a value that identifies the exception. Depending on the value in XML-CODE, the parser might or might not be able to continue processing after the exception, as detailed in the information referenced below.

XML conformance
The built-in COBOL XML parser that is included in COBOL for AIX is not a conforming XML processor according to the definition in the XML specification. The parser does not validate the XML documents that you parse. Although it does check for many well-formedness errors, it does not perform all of the actions required of a nonvalidating XML processor.

XML GENERATE exceptions
One of several exception codes might be returned in the XML-CODE special register during XML generation. If one of these exceptions occurs, control is passed to the statement in the ON EXCEPTION phrase, or to the end of the XML GENERATE statement if you did not code an ON EXCEPTION phrase.
