endDocument() must be called before the SAXParseException is thrown (from
the specification of 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"

If endDocument must be called then I can't see how the parser can justify
not calling the other methods. I would also expect a call of characters()
after startElement(child2).
