Hi Andreas,

This may just be a documentation bug - if memory serves me correctly, I
didn't necessarily run the traversal to create that output, although I
think you could easily modify the example code on that page (
to generate similar output.

I don't have a boost checkout handy right now to verify that it's just a
documentation bug, but I'll try it out tonight and reply to this thread
