How hard the problem is depends to a great extent on whether the 
delimiter (markup or pseudo-markup) can be buried deep in the node, 
or whether it can split only children.

If the former, it can be necessary to flatten and then induce a new 
hierarchy. (This is actually a special case of an overlap problem.) 
But it appears that James only has to do the latter.

Cheers,
Wendell
