Based on the provided BPMN XML, I've listed out the tasks (tasks, subprocesses, and events) in the process model. However, since the XML doesn't contain any task details (like names or labels), I've used the generated IDs for identification.

1. **idb86a1356-bb12-4a45-ba13-d430cf587b6b** - Task/Event/Subeprocess start
   - This ID is a sourceRef in one of the sequence flows, indicating it's the start of the process.

2. **id3152b404-1b39-4c61-bff7-e4e507f627a** - Task/Event/Subeprocess
   - This ID is a sourceRef in two sequence flows, indicating it's a task or the start of a subprocess.

3. **id25fcead3-d54b-47a1-b9dc-5ac5df8a31db** - Task/Event/Subeprocess
   - This ID is a sourceRef and targetRef in sequence flows, indicating it's a task or the end of a subprocess.

4. **idd371ddf5-0e93-4afa-bd26-49c2c4bc293e** - Task/Event/Subeprocess
   - This ID is a sourceRef in one sequence flow, indicating it's a task or the start of a subprocess.

5. **idc5b9256f-0a5c-43f7-9877-8a7d17977ee2** - Task/Event/Subeprocess
   - This ID is a sourceRef and targetRef in sequence flows, indicating it's a task or the end of a subprocess.

6. **id34fba6ea-bbb7-47b7-94a8-3417ede3ceef** - Task/Event/Subeprocess
   - This ID is a targetRef and sourceRef in sequence flows, indicating it's a task or the start of a subprocess.

7. **id3fe498e9-097b-4628-96b0-639beba726c7** - Task/Event/Subeprocess end
   - This ID is a targetRef in one sequence flow, indicating it's the end of the process.

8. **idd3814e0c-ae8b-41d6-b7a1-7c0e9385eb3e** - Task/Event/Subeprocess
   - This ID is a sourceRef in one sequence flow, indicating it's a task or the start of a subprocess.

Here's a simple representation of the process flow:

- Start: idb86a1356-bb12-4a45-ba13-d430cf587b6b
  - Task/Subprocess: id3152b404-1b39-4c61-bff7-e4e507f627a
    - Task/Subprocess: id25fcead3-d54b-47a1-b9dc-5ac5df8a31db
    - Task/Subprocess: idd371ddf5-0e93-4afa-bd26-49c2c4bc293e
      - Task/Subprocess: idc5b9256f-0a5c-43f7-9877-8a7d17977ee2
  - Task/Subprocess: id34fba6ea-bbb7-47b7-94a8-3417ede3ceef
    - Task/Subprocess: id3fe498e9-097b-4628-96b0-639beba726c7 (End)
  - Task/Subprocess: idd3814e0c-ae8b-41d6-b7a1-7c0e9385eb3e
    - Task/Subprocess: id34fba6ea-bbb7-47b7-94a8-3417ede3ceef (End)
