12.4 Example(s)
This sub clause provides examples to support interpretation of the BPMN DI specification. Some BPMN diagram depictions along with their XML BPMN DI serializations are provided. The XML samples provided in this sub clause present only BPMN DI instances and omit the BPMN 2.0 abstract syntax.
For readability purposes, the bpmnElement that is referenced by the BPMNPlane, BPMNShape, and BPMNEdge use a representative string pattern. This string pattern is:
BPMNModelClassName_BPMNModelNameAttributeValue
For example: “Task_Activity” for a Task named “Activity.”
In the provided XML serializations, the di namespace refers to the Diagram Interchange namespace defined in Annex B, and the dc namespace refers to the Diagram Common namespace also defined in Annex B.
12.4.1 Depicting Content in a Sub-Process
This sub clause shows various ways of depicting the content of a Sub-Process of the same BPMN model.
The BPMN model contains a process composed of a none start event (named “StartEvent”), a sub-process (named “SubProcess”) and a none end event (named “EndEvent”). There is a sequence flow (named “a”) between the start event (named “StartEvent”) and the sub-process (named “SubProcess”) and a sequence flow (named “d”) between the subprocess (named “SubProcess”) and the end event (named “EndEvent”).
The sub-process (named “SubProcess”) is composed of a none start event (named “SubProcessStart”), an abstract task (named “Activity”) and a none end event (named “SubProcessEnd”). There is a sequence flow (named “b”) between the start event (named “SubProcessStart”) and the task (named “Activity”) and a sequence flow (named “c”) between the task (named “Activity”) and the end event (named “SubProcessEnd”).
Expanded Sub-Process
First, a BPMN diagram depicts the BPMN model with the expanded sub-process showing its content (see Figure 12.8). This leads to a BPMN DI serialization of a single diagram that depicts this process (see Table 12.37).

Expanded Sub-Process with Start and End Events on Border
An alternative to depicting the same BPMN model of 12.4.1 would be to place the sub-process start and end events on the border of the sub-process (see Figure 12.9). In the BPMN DI serialization of this diagram (see Table 12.40), the target of the sequence flow named “a” and the source of the sequence flow named “d” are the start and end events on the boundary of the sub-process.
Compare the target of the sequence flow named “a” and the source of the sequence flow named “d” of Table 12.37 with that of Table 12.38.

Collapsed Sub-Process
Alternatively, one could depict the same BPMN model of 12.4.1 as two diagrams. A first diagram (Figure 12.10) depicts the process with the sub-process collapsed, while a second diagram (Figure 12.11) depicts the content of the sub-process.
