Paragraph sequence diagrams in the case study, chapter 8 (Sun Certified Enterprise Architect for J2EE Technology) by Mark Cade.

Quotation:
Sequence diagrams at the architectural level structure the components and dicate a flow of events through the components. These diagrams are not using classes or objects, but components to provide the developer with some guidelines for developing a detailed design of the system.


The sequence diagrams show ValueObjects that are not shown (and do not have to be shown?) in the class or component diagram. This seems to contractict the quotation above.
Is it ok to show objects (in this case ValueObjects) in the sequence diagram. Will I loose points if I do or will I loose points if I do not?

Did anybody get a good grade with very similar sequence diagrams?

Lukas,

Try to forget what some book says or what some article has been sad, and concentrates in create the logical architecture based on your experience. As an candidate architect, you should be aware about how to create an architecture.

There is no right answer to your question, use your instincts. Mark Cade diagrams does not make any sense at the real world.

Regards,
