Your definition is extremely weak; using it, one can make *any*
problem "out of scope" simply by dropping them from a spec.  This is
clearly not useful.

A useful definition of what is in-scope is what would need to be
implemented to make the described technology work.  For the spec in
question, that includes the CDMs that are expected to be plugged in.
We don't need to discuss precise implementation details, but the
overall properties of the CDMs *are* important, because they'll be
used in conjunction with this technology.

I'm sorry that you don't understand how to bridge this gap.  Your
refusal to discuss CDMs, though, will not stop the discussion of CDMs
by other people, nor will it help convince anyone who has reservations
about the CDMs to support the proposal.
