My thinking in the shower this morning was:

 #step-name/childstep-name^port-name
 #step-name/step-name$option-name

So #step-name finds the first (in document-order) step named
'step-name'. If that's not unique, you can do:

  #step-name/childstep-name

which finds the first step named 'childstep-name' that is a child of
the first step named 'step-name'. Repeat as deep as you need.

I think that our rules for the scope of step names guarantee that that
simple algorithm will always uniquely find a step.

I don't think we need to support pointing to p:logs or p:parameters.
But we could invent something more complex if we needed to.
