The MIME types for renderer selection is not a new idea. But I don't know anymore when it came up for the first time.
The idea is to eliminate the hardcoded references to the renderers. That way it's easier to include new ones or special-purpose renderers subclassed from existing ones. Instead of wiring the renderers to FOP using Java code we will do it using XML, or more concrete: The component setup XML which will be used to build the Avalon-style ComponentManagers/ServiceManagers. The MIME types could then be used as role names used to lookup the renderer component (See Avalon docs for roles, component lookup etc). As for subclassing (I'm not sure what exactly you're referring to), we won't need to change the current class hierarchy as far as renderers are concerned. Only some cleaning up and a little bit of refactoring will be required. The only big thing we change is the way we get the renderer. > I'd actually like to hear more about this.
