Right. I made it possible to construct a parameter set that included
them, but I didn't make it possible to get at them as a document.

I'd have said:

   <p:declare-step type="p:parameters">
     <p:output port="result" sequence="no" />

and I'd have said the semantics of this step is that it returns, as a
c:parameters document, the set of parameters passed to it. So the
parameters passed to the pipeline are exposed with:

  <p:parameters use-parameter-sets="#default"/>

In my proposal, the parameters are passed around as c:parameter
elements in a single c:parameter*s* document.

I guess I'd be happy to discard the c:parameters wrapper and just use
a sequence of c:parameter documents.

I'm going to take the fact that Henry, Jeni, and I are in apparent
agreement as a very optimistic sign and rewrite my proposal to
incorporate the changes that Henry and Jeni suggested.

                                        Be seeing you,
