How to model that. Maybe best to be silent on this. This seems completely natural if the reference is just a URL binding, instead of seeming puzzling. A direct reference creates a binding. Jim W thinks yes.
Members are always just a path segment.
The ordering is embodied in the internalmembers property. It turns out that Jim and Geoff had in mind different semantics for direct references. Jim was thinking of something like hard links, Geoff was thinking of something like soft links. So it s really a new binding that gets created. In case you get moved.
