I am not 100% we have built a strong case for parameters. It looks like 
they are only needed for XSLT. Do we have other use cases?

This was one of the motivations to go toward the XDM: whether you are 
talking about "inputs" or "parameters", there would be no difference 
with the XDM.

My fear is that now, will will have two concepts: "input" and 
"parameters". They won't work the same, and the question of how or 
whether a step can produce data which gets connected to a "parameter" 
remains open.
