Without thinking too much about it, I'd say that overlays seem to be
a better fit: each node is an overlay, the node's attributes can be stored
in the overlay's properties, the text corresponding to a node can be stored
directly in the buffer and retrieved by (buffer-substring (overlay-start o)
(overlay-end o)), ...
