I had a discussion with Uche on similar issues a few months ago. He
pointed out that the id could be floats, which means that, to a certain
extent, inserting a node in the middle of the tree didn't require that
the ids of nodes after the inserted one (in document order) had to be
updated. You just have to set the id of the new node to 
0.5*(id_before+id_after).
