I agree. The word "interpretations" in C6 can't have been intended to
include the interpretation of code points qua code points. That would
make a great many internal processes impossible.

I think of C6 as meaning that spell-checkers, for example, should not
treat José (NFC, four code points) and José (NFD, five code points)
as separate entries.
