Right - but the behaviors / significance of using each object might be very different based on subtype. A website's Content Management System (CMS) basetype might offer short name, long name, and permissions related attributes, which might be enough to write large amounts of code managing large parts of the website's infrastructure, and yet the subtypes might be as different as a web bookmark and a Flash game.
