So if a publisher has produced two books with the same ISBN then one
doesn't exist? Suggest for "_are_" read "_should be_" - unless there's a
handy way to get this right other than just asserting that data is
wrong? In the past the uniqueness of ISBNs was obviously seen as
unimportant. Maybe a disambiguation rule that uses IFP for new-style
ISBNs (which, one might hope, will be safely assigned in the future).
