This could be the name of a queue or topic defined in the broker.
With topic tree, if the metadata queue name is not specified, the name of the metadata queue will be constructed according to the topic tree rules.
When all queue names (such as QueueName and MetaDataQueueName) are unspecified (empty strings, which are the default), and the 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 QueueName or 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.
