BPMN2 — How to represent Process Diagrams and Lanes?

Taking Figure 10.121 as an example, it’s unclear what the outer box represents in the diagram – is it a graphical Pool representing a Participant named Supplier linked to a PartnerEntityRole also named ‘Supplier’ in turn linked to a Process also called Supplier? Or is it merely a Process called Supplier (in which case it could be better named ‘Supply Process’)? I would have thought the latter, but that does not tie in with my reading of 13.2.3 which states that “A Lane is a sub-partition with a Pool” and “A Pool is the graphical representation of a Participant in a Collaboration (see page 146). It is also acts as a graphical container for partitioning a set of Activities from other Pools, usually in the context of B2B situations.” Likewise Figure 13.4 provides only one interpretation – as Lanes within a Pool not within a Process.

Though Table 13.1 states that a Process Diagram has at least one LaneCompartment (which is inconsistent with 13.2.3 which states that Lanes are only within Pools) this is inconsistent with the serialization (in Table 10.19) of Figure 10.23 which has no instance of Lane at all. And Figure 10.23 appears to use the Pool notation shown in Figure 13.3
