I'm going to disagree here. The goal of this document is to make it simple
for authors to identify code-point repertoires without having to become
Unicode experts. I think the explanations we have come up with so far are
acceptably clear and rooted in the Standard without needing introduce the
“assignable” notion.  Wait till you get a look at the next revision to see
if you want to continue to argue this point.

OK.
