  • B: False



Question 2
The Messaging Metadata pattern requires a messaging framework that supports the processing of messages with headers or properties.

  • A: True
  • B: False



Question 3
Which of the following statements is false?

  • A: Widespread use of the Messaging Metadata pattern can be seen in the emergence of many WS-* extensions that define industry standard SOAP header blocks that carry metadata.

  • C: The Messaging Metadata pattern is not applicable to situations where the message sender and receiver need to participate in stateful or conversational message exchanges.
  • D: The Messaging Metadata pattern can support the application of patterns such as Intermediate Routing by supplementing messages with activity-specific metadata.
