In private email, I was asked:

| 4.1 In some cases, compound steps can contain implicit primary output
| ("result") that is created when the compound has no declared output step
| and the last step of the subpipeline has an unbound primary output (spec
| section 2.3). How does a declaration of this primary output look like?
| In our implementation, the implicit primary output always accept
| sequences of documents (sequence="true")

I replied:

I think that needs to be made more clear. I think it should inherit
the properties of the output declaration on the last step. So if the
last step produces a sequence, then so does it, but not otherwise.

Anyone disagree?
