Considering this position, I came to the same conclusion. However, when
considering the SAX universe on whole it makes absolute sense that
endDocument be guaranteed. Many developers simply write pass-through filters
based on ContentHandler. In these black-box pipeline classes there is no
call to parse around which one should place a finally-- they must be
autonomous in there intialization and finalization.

For this reason I feel that the Xerces implementation is in error. I ran a
quick survey to see how the major parsers break down-- I haven't had a
chance to test MSXMLs SAX implementation yet.

AElfred2 : fires endDocument
XP : fires endDocument
Oracle V2 XML Parser: does not fire endDocument
crimson : does not fire endDocument

Expat : fires endDocument
