I read through the X tree paper again. I agree that the DescentType is not specified... the paper just says in Figure 7:
```
follow = choose_subtree(obj);
```
And there is no explanation of what `choose_subtree()` is, so I think it's safe to assume that it's the typical R tree heuristic. (Maybe it would be possible to use the R* heuristic too, but, I think sticking with the default is good for the X tree typedef.)
Ball trees aren't added to allkrann because of a tricky bug:
