Remarks
The DCPSSubscription topic communicates the existence of DataReaders by means of the SubscriptionBuiltinTopicData datatype. Each SubscriptionBuiltinTopicData sample in a Domain represents a datareader in that Domain: a new SubscriptionBuiltinTopicData instance is created when a newly-added DataReader is enabled, and it is disposed when that DataReader is deleted. An updated SubscriptionBuiltinTopicData sample is written each time the DataReader (or the Subscriber to which it belongs) modifies a QoS policy that applies to the entities connected to it.
