They all depend on whether "Publication Post-Processing" should be
able to access content *beyond* what enters the publication process.
I'm not sure what you are getting at here.
We need a definition what we mean with pipelines. I understand them
with a unix-background, where elements of a pipeline are working on
the result of the earlier elements. This is data driven, so a
pipeline element does only get the information in the data plus some
parameters. Paul probably means the reaching back of the pipeline
elements in the application-server context. For example are the
pipeline elements be called by a controller, which additionally holds
the context of the object in the application space.
In contrast the elements could purly be data driven, working on xml-
data and nothing else. This looks more defined and is probably be
simpler, but I see and fear that then parameter stuff is encoded in
the xml-data to steer some transformations later in the pipeline.
