So the "trivial" way to do it (and the way we have implemented the FW

the slot node.

This is what Gavin proposed patches do.

The overlay mechanism adds all sorts of features that we don't seen to
need and would make the above more complex.

Guys, I never got a final answer from you on this. Are we ok with adding
the way to just expand a subtree or are you insistent we need to use the
overlap mechanism ?

Cheers,
