If we were talking about a virtual generator, I'd agree with you. But, after 
introducing the concept of "sitemap services" which are, from a users 
perspective like a web service, they become the source in my opinion.

And here we disagree ;-)

The CSV file is important for the called service but for the calling pipeline, 
it is just some data that is passed. The servlet service generator parses the 
output stream returned by the called servlet and not the CVS file.

                                   - o -

I think that continuing this discussion doesn't solve the problem. Maybe we 
should start a poll on dev@, how others (except from Jörg, Alex, Grek, Vadim you 
and me) think about it because I guess that most of them probably don't follow 
this long thread anymore.
