Actually... We _COULD rework DTM so the root node is 1 and DTM_NULL is 0,
rather than 0 and -1 as now. We could do something similar with the columns
which point to other kinds of data.

It'd be a lot of fiddling detail work, but it's doable. I'm not convinced
it's a high priority. Something to ponder.
