Remarks

The default behavior is that for a PubSub object descriptor to be strictly physical, it must not have a (non-empty) logical name. The behavior of derived descriptors may differ.

With transport profiles that use JSON, the writer group descriptor is always strictly physical. With other transport profiles, for a writer group descriptor to be strictly physical, it must not have a (non-empty) logical name.
