Excerpt
Introduction: When supplying a data stream service between a provider and a consumer, the need to provision the use of other application entities, in addition to the provider and consumer, may arise. For example, some party may wish to customize a data stream as a service to a consumer. The customization step might be based on the customer's resource availability (e.g., display capabilities).
