Previous topic model in postUpdateTopic-hook lacks children values
This is a follow-up of dmx-plugins/dmx-notifications#11 (closed)
The reason why this would be good to have is the "value" topics can never be updated as of DMX 5.1. Thus, postUpdateTopic is useless, if one would for e.g. monitor the changes in a "dmx.notes.text" field. The only way to react to content changes of a "Note" topic is exyctly by "listening" updates on its parent topics.
