My 10 cents. I'd find it more natural if the behaviour was changed so that applying it multiple times caused the test to be run multiple times, once for each test. The reason I say this is I'm sure I saw Charlie mentioning comma separating the list of cultures. That's fair enough, but if you can apply the attribute multiple times, you don't need to know that to run the test for multiple cultures you need to comma separate the arguments.
