Remarks Message objects are used to represent all outputs from the API including
subscription data, response, administrative and status messages. Message
objects are obtained from Event.GetMessages().
A message always has a message type and may optionally contain the following
| TopicName | Valid for Subscription data messages. |
| Service | The service from which this message was received from. |
| CorrelationId | One or more correlationIds if this message was delivered for a pending request or a subscription. |
A Message object is a handle to a single underlying protocol message. The Message contents are represented as an Element and some convenient shortcuts are supplied to the Element accessors.
