If they are to define collation, they have to define how the order results from the tailoring. Of course, it can be done by reference, but while saying 'as in UCA' is entirely appropriate where the UCA is adequately defined (some tailorings clearly are not, and work is under way to fix some of these shortfalls), I am uneasy at 'as in ICU'.
