Yes. I agree with you, and considering this your way of handling
additional content seems more appropriate.

This "vision" of the intermediate tree is also what has triggered my
last question: why do we want to model class/type information
(associated with the lens selector) in the intermediate tree, and if we
need a reference to the lens that generated a particular fragment of the
tree, why not simply reference this lens directly (and thus unambiguously)?
