I also think that in many (if not most) of those cases, the sequence is not
managable by sequence numbers or any other document-local rules, but
requires interaction with something like actual business objects at one or
both ends of the collaboration.
...
In other words, sequencing of business collaborations may require
collaboration software with some business intelligence, it may not be
manageable exclusively by sequence numbers or linked lists.

I don't know whether "the sequence" and "sequencing" would be the best terms
(I might rather use something like "Temporal constraints between (Economic,
Business?) Events"), but I strongly agree with the assertions: "is not
manageable by sequence numbers or any other document-local rules" and "it
may not be manageable exclusively by sequence numbers or linked lists".
