Oops! Of course, I really meant:

    All we can do is to define compatibility equivalence (NFK*)
    between:
        <c1, CCO, c2>
    and:
        <c1, c2>
    unless:
        CC(c1) > CC(c2) > 0.

More formally:
    { NFKC(<c1, CCO, c2>) = NFKC(<c1, c2>),
    and NFKD(<c1, CCO, c2>) = NFKD(<c1, c2>)
    }
<=> not
    { CC(c1) > CC(c2),
    and CC(c2) > 0
    }
<=>
    { CC(c1) <= CC(c2),
    or CC(c2) <= 0
    }
