With respect, I think it's important _not_ to conflate inputs and
parameters.  This connects up with our discussion on the call
yesterday:  inputs, in the prototypical case at any rate, are XML
documents, whereas parameters are (or are adequately modelled as)
name-value pairs.  Not at all the same thing, and confusing to try to
use a single term to cover both.
