Thank you Franklin -- yes, "weights" is the right word.
I'll correct in a minute.
> It is IMO better to describe these as "weights" rather than "labels".
So what you are defining are "hetero-weighted trees", the requirement
is that each node has a distinct positive integer weight, and the
weight of any non-leaf node is the sum of the weights of its children.
