That's my inclination too.  But I'm not sure it'd be good to require it.

I think it is:

    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.

Re how many parsers do this correctly, I'm not sure.  My enhanced AElfred
does (now), but I think many others don't.

See above -- a thrown exception is "an unrecoverable error".

In Java, try/finally does a fine job of letting the parser call
the endDocument() handler even in that case.
