Not explicit in the CR? Unless I missed it?
 How'm I supposed to intuit this Norm?
With a pipeline of a single atomic step I'm thinking I am controlling where it's
output goes, i.e. they are one and the same thing?

Hence I see that as

  input from a.xml
  output to b.xml

That seems quite logical to me.. Yet clearly doesn't fit the
model you have.

I guess it's down to the lack of symmetry.
