Counter-argument: in my first SAX application, I knew what attributes to
expect, so I was able to write:

public void startElement (String name, AttributeMap atts)
  {
    String id = atts.getValue("ID");
    String ref = atts.getValue("REF");
    ....
}

This would be MUCH more clumsy with James' proposed interface!
