An error occurred because the parser could not start or could not continue parsing.
While SAX-PARSE( ) is running, each time the parser detects an XML element, the AVM invokes the corresponding callback. Callbacks reside in a procedure file whose handle has been assigned to the HANDLER attribute.
Note: SAX-PARSE( ) does not have a return value. To detect if an error has occurred, add NO-ERROR to the call and when it returns, check ERROR-STATUS:ERROR.
