Yeah, Jave truly rocks. I found it googling some days back, and since 
then I got addicted. Really awesome.

Oops, sorry, sometimes I think in terms of abstractions and use 
"personal" names. My wife is always picking on me as when I am excited I 
do not pick words correctly and the sentnces look all mixedup! ;-)

Well, to summarize, Cocoon has a double parallel system: the object part 
and the XML pipeline part. With context I intended the object part.

Usually I call the first "environment" and the other the the "pipelines"...

Hope it's a bit clearer now.

I think so.

Yes, IMHO we need another concept, and present it in the sitemap.

Before, I had called it "locators", as a Generator should generate XML, 
not really care where the data comes from.

Then we had source protocols, that seemed to have resolved all 
pre-generation problems, as it basically does what a "locator" should do.

But hey, guess what, we came up with "input modules", that act similarly 
to sources in the "context/objectspace/environment" part.

And now we are talking of making a unified view of these?
