In the followup of Alex's reply, I also believe parameters should be 
separate from inputs. If we want to reuse some pipeline, we may allow 
its reuse through parameterization. This enforces some standardization 
of parameter specification for (at least) XSLT and blackboxed pipelines.

My feeling is that parameters should not be bound to data, but to 
component configurability. Therefore, we should be careful on allowing 
connection between data and parameters.
