No, not really. At least not personally :-)

Yeah.

That suggests that you think there would be some value in allowing
p:declare-step elements to be sprinkled throughout a pipeline or
pipeline-library.

I like the conceptual neatness of putting them all at the top,
independent of the fact that this means the processor sees the
declarations first.

I like Henry's argument advanced in support of p:input*,p:output*,p:param*
(as opposed to (p:input|p:output|p:param)*): if the order is irrelevant,
pick one and enforce it.
