Strange SAX2Count behaviour

Hi there,
I was playing with SAX2Count and among others I tried the following 2 
test cases where I took the xml stuff from the samples as well.

1. I have a personal.xml where I changed the DTD name to something
which does not exist.

When now calling: SAX2Count -v=never personal.xml 
I get

Fatal Error at file ....
  Message: unable to open DTD document ...

2. I have a personal-schema.xml where I changed the schema name to
something not existing.

When now calling: SAX2Count -v=never personal-schema.xml
I get

Warning at file...
   Message: unable to open primary document entity ....


Question: Why do I get a warning in case 2 but a fatal erros in case 1?
What could I do to prevent the DTD not found message to be fatal.

Well I added this in the error handler which does work:


void SAX2CountHandlers::fatalError(const SAXParseException& e) {
	const XMLCh *emsg = e.getMessage();

    const XMLCh *dtdmsg = XMLString::transcode("unable to open DTD
    document");

	// We want to make it a warning if dtd will not be found
	if ( XMLString::compareString(emsg, dtdmsg) ) {
	  warning(e);
	  return;
	}
    fSawErrors = true;
    XERCES_STD_QUALIFIER cerr << "\nFatal Error at file " <<
	StrX(e.getSystemId()) << ", line " << e.getLineNumber()
                              << ", char " << e.getColumnNumber()
                              << "\n  Message: " <<
	StrX(e.getMessage()) << XERCES_STD_QUALIFIER endl; }           


However, I could imagine there is something better I could do.
