Using the topic tree has two major effects:
When all queue names (such as OpcLabs.EasyOpc.UA.PubSub.Configuration.UABrokerDataSetReaderTransportParameters.QueueName and OpcLabs.EasyOpc.UA.PubSub.Configuration.UABrokerDataSetReaderTransportParameters.MetaDataQueueName) are unspecified (empty strings, which are the default), and the UAPubSubConnectionDescriptor.EffectiveTransportProfileUriString in the ConnectionDescriptor is for transport that uses the topic tree (such as MQTT), the EffectiveAssumeTopicTree becomes true, and you do not have to set AssumeTopicTree to true explicitly in order for the topic tree to be assumed.
CAUTION: With the topic tree (AssumeTopicTree set to true), do not set the queue names by setting values of OpcLabs.EasyOpc.UA.PubSub.Configuration.UABrokerDataSetReaderTransportParameters.QueueName or OpcLabs.EasyOpc.UA.PubSub.Configuration.UABrokerDataSetReaderTransportParameters.MetaDataQueueName, except in very special circumstances. Leave the queue names at their default values, i.e. empty strings. Setting queue names can interfere negatively with the built-in mechanism that determines the proper topic filters.
