Hello, Bram. I guess [child] was recently extended. Docs might be outdated, don't hesitate to contribute doc improvement. [subquery] is a neat thing, it's just queries without relying on particular use case, if my understanding is right one may request something like _path_ field in [subquery], which may let to reconstruct hierarchy.
