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.
