The code is as I have it at the moment. The documentation [1] does not
mention that Collection::fromUrl() only returns a partially usable
Collection instance. It might be worthwhile to add that.

If I add a CollectionFetchJob, does that automatically enhance the
Collection instance for which I already have a handle (in m_collection),
or do I need to get the final instance from the fetch response?

Bye, Patrick
