Right.  See comment below under #3.

Only inasmuch as the usage is really limited to this particular binding, and
not expected to be either implemented by or referred to by other
extensions/bindings.

Yup - the key here is that you do not actually have to talk about ALL these
things in your particular binding, and in fact we may not (and hopefully
will not) even define all these things in the context of the WG's output.
The binding framework gives you a place to hang connections between your
binding and specified facets such as the ones you mention in your list.  We
as a WG take on defining a very small number of these facets, and a very
small number of bindings, and then let other groups or communities do the
rest.

Seems right.

I hope so!
