DDS_WriterDataLifecycleQosPolicy	autopurge_unregistered_instances_delay

DDS_WriterDataLifecycleQosPolicy	autopurge_disposed_instances_delay
	<<extension>> Maximum duration for which the DDS_DataWriter will maintain information regarding an instance once it has disposed the instance.

DDS_ReaderDataLifecycleQosPolicy	autopurge_nowriter_samples_delay
	<<spec>> Minimum duration for which the DDS_DataReader will maintain information regarding an instance once its `instance_state` becomes DDS_NOT_ALIVE_NO_WRITERS_INSTANCE_STATE.

DDS_ReaderDataLifecycleQosPolicy	autopurge_disposed_samples_delay
	<<spec>> Minimum duration for which the DDS_DataReader will maintain samples for an instance once its `instance_state` becomes DDS_NOT_ALIVE_DISPOSED_INSTANCE_STATE.

DDS_ReaderDataLifecycleQosPolicy	autopurge_disposed_instances_delay
	<<extension>> Minimum duration for which the DDS_DataReader will maintain information about a received instance once its `instance_state` becomes DDS_NOT_ALIVE_DISPOSED_INSTANCE_STATE and there are no samples for the instance in the DataReader queue.

DDS_ReaderDataLifecycleQosPolicy	autopurge_nowriter_instances_delay
	<<extension>> Minimum duration for which the DDS_DataReader will maintain information about a received instance once its `instance_state` becomes DDS_NOT_ALIVE_NO_WRITERS_INSTANCE_STATE and there are no samples for the instance in the DataReader queue.

DDS_DataReaderResourceLimitsQosPolicy	max_total_instances
	<<extension>> Maximum number of instances for which a DataReader will keep state.

DDS_DataReaderResourceLimitsQosPolicy	keep_minimum_state_for_instances
	<<extension>> Whether or not keep a minimum instance state for up to DDS_DataReaderResourceLimitsQosPolicy::max_total_instances.

DDS_DataReaderResourceLimitsQosPolicy	instance_replacement
	<<extension>> Sets the kind of instances allowed to be replaced for each instance state (DDS_InstanceStateKind) when a DataReader reaches DDS_ResourceLimitsQosPolicy::max_instances.

DDS_DataReaderResourceLimitsQosPolicy	autopurge_remote_not_alive_writer_delay
	<<extension>> Maximum duration for which the DDS_DataReader will maintain information regarding a DDS_DataWriter once the DDS_DataWriter has become not alive.

DDS_DataWriterResourceLimitsQosPolicy	instance_replacement
	<<extension>> Sets the kinds of instances allowed to be replaced when instance resource limits are reached.

DDS_DataWriterResourceLimitsQosPolicy	replace_empty_instances
	<<extension>> Whether or not to replace empty instances during instance replacement

DDS_DataWriterResourceLimitsQosPolicy	autoregister_instances
	[DEPRECATED] <<extension>> Whether or not to automatically register new instances

DDS_DataReaderProtocolQosPolicy	propagate_dispose_of_unregistered_instances
	<<extension>> Indicates whether or not an instance can move to the DDS_NOT_ALIVE_DISPOSED_INSTANCE_STATE state without being in the DDS_ALIVE_INSTANCE_STATE state.

DDS_DataReaderProtocolQosPolicy	propagate_unregister_of_disposed_instances
	<<extension>> Indicates whether or not an instance can move to the DDS_NOT_ALIVE_NO_WRITERS_INSTANCE_STATE state directly from the DDS_NOT_ALIVE_DISPOSED_INSTANCE_STATE.

DDS_DataWriterProtocolQosPolicy	disable_inline_keyhash
	<<extension>> Controls whether or not a keyhash is propagated on the wire with each sample.
