This is not how this works. As soon as the undefined entity is 
detected a fatal error is reported. the parser may not then continue 
to report the remainder of the content of the document in the usual 
way. This is according to the XML 1.0 specification, not SAX 
specifically. Fortunately I've only seen one uncommon parser that 
does this wrong, and continues to call startElement after a 
fatalError.

I guess what you're saying is logically endDocument should be called 
only if the end of the document is seen. Logically that make sense. 
However, the SAX docs are clear that this is not the case. 
endDocument really indicates the end of parsing, not the end of the 
document. It is not incorrect to call endDocument after a fatal error.
