It also raises a bit of a bugbear for Xerces, as it checks for 
fatalError correctly. When Xerces encounters a fatalError, it doesn't 
call endDocument afterwards. The SAX specification mandates that 
endDocument is always called. So this patch reduces Xerces conformance 
to 37.28%.

From the SAX specification for endDocument:

"The SAX parser will invoke this method only once, and it will  be the 
last method invoked during the parse. The parser shall  not invoke this 
method until it has either abandoned parsing  (because of an 
unrecoverable error) or reached the end of  input."

In the conformance tests for Xerces, the last method invoked is often 
fatalError NOT endDocument, which I interpret as a fail.
