Following the discussion on the comments list, I think the proposal is
to allow p:choose and p:try to have subpiplines where there are
outputs that are sometimes a sequence and sometimes a singleton, with
the semantic that a sequence is allowed if any subpipeline specifies a

And to add a primary result document to p:error which always produces
an empty sequence.

I have reservations about making these changes without going back to
last call. I'm prepared to be persuaded, but...

                                        Be seeing you,
