John, thank you for your helpful reply.
What I mean is there is more than one co-author who needs to submit
forms. There is a large concurrent workflow happening while the co-
authors may be submitting their forms. In other words:
1) Author submits a paper.
2) Co-authors begin submitting forms (may be concurrent with the
following steps).
3) Paper goes through review and revision processes.
4) Final decision is reached.
5) If paper is accepted for publication, the co-authors' forms are now
due.
6) Paper is published.
It seems to be most like your first example:
---8<---
concurrence :count => 1 do
concurrent_iterator :on_f => '${f:coauthors}' do
# ... iterations ...
end
sequence :lose => true do
# ... something else ...
end
end
--->8---

I don't want the sequence to be lost. The sequence is the main process
but the concurrent_iterator may be lost (in the case the paper is
rejected). If the paper is accepted, then the concurrent_iterator must
be completed.

Reed
