Whoa, you've lost me. What's the concept here? I thought the purpose of
the editor interface was to communicate changes, and that it was
designed to be serialised onto the wire for transmitting changes from
one place to another. I thought it used deltas because that's normally
the most efficient way to represent a change.
I note that it uses deltas to represent tree changes - "Add this node,
delete this node," rather than "The resulting tree will be, in full: X
X/Y X/Y/Z". (With "deltas" just meaning differences, not a particular
encoding.)
It feels like I'm missing the big picture. Help, please!
