The complete interaction consists of two point-to-point messages—a request and a response. The interaction is only considered complete after the response has arrived.
• Publication (notification) means an operation sends information on an as-needed basis, potentially multiple times.
• Subscription means incoming information is processed on an as-needed basis, potentially multiple times.
