Andreas Pieber updated COCOON3-22:
----------------------------------

    Attachment: StAX-classes.png

I'm not quite sure what I should think about this idea. On one hand it would eliminate not really required interfaces which is quite a good idea, but on the other hand it would (IMO) also create complexity on an other side. I attached a very simple class diagram of the cocoon-stax component. If you replace StAX (in the names) with Image you'll see the base architecture of the image-component proposed by Steven. Replacing StAX with SAX would produce the very basic architecture of the cocoon-sax module. And replacing StAX with any other name will (hopefully) produce the base architecture of any other future pipeline module.

So, if you're familiar with one component (e.g. StAX) you can very easily transfer your knowledge to any other component, since the basic architecture (NAMEProducer, NAMEConsumer, ...) is the very same throughout all components. From that point of view it may be a better idea to rename XMLConsumer and XMLProducer to SAXConsumer and SAXProducer instead of removing them.

Of course I'm not sure in how far this assumption will hold for all future components...

WDYT about that?

> Remove XMLConsumer interface; relying on a content handler which might optionally implement lexical handler is sufficient and simplifies the module
