Nice wording.

yes

and that would be edited, right?

To the implementor, right?

If we allow several expressions associated to a blank then it also makes sense to allow one that allows the recipient user-agent (e.g. a web-page with some javascript) to compare the user-input with the one (given some flexibility).

My concern now is whether it is good to allow multiple children. From this discussion it sounds unavoidable. And if we do so, how do we markup so that renderers that are unaware of this note still render something partially useful?
