Subject: Handling xercesc::DOMException in "read-xml-file" and
 "external-text-formatter" * external DOM may cause xercesc::DOMException's to
 be thrown instead of passing all errors to the custom error handlers ** these
 exceptions are handled by this commit by setting the "result" attribute to
 "error" and adding "error" value nodes with further information
