That's ugly. Perhaps the startDocument() guarantee should be expanded to
say that it'll be called before any other method in *any* of the
handlers (instead of just ContentHandler and DTDHandler, as it states
now). I'd think that the only error conditions that can occur prior to
what I'd consider the start of the document are IOExceptions, which
don't need to go through the ErrorHandler.
