Having read through this thread, I want to ask a perhaps naive
question: why are we requiring parameter declarations at all?
We seem to be converging on the
option:parameter::pre-known:not-pre-known
story. So what are we actually accomplishing by trying to declare
parameters? The 90% case will surely be <p:parameter name="*"/>,
which carries almost no information. . .
So I offer a tentative but radical proposal:
1) No more parameter declarations.
2) Parameter _binding_ is OK -- you may want to give a parameter a
value in a pipeline or group or step -- fine.
3) No more parameter importing -- it likewise serves no purpose --
all in-scope parameters are available to a step.
4) But preventing parameter name clashes _is_ sometimes needed, so
replace p:import-parameters with
<p:parameters from-ns="...." to-ns="...."/>
