For those languages, the parser would invoke the warning() or fatal()
callbacks to report an IO problem, and your handlers could set a
status variable. For all SAX implementations, any invocation of
fatal() means that your document is probably corrupt, is not
guaranteed complete, and should not be processed (except for
error-reporting purposes).
All the best,
