    This is exactly like none_or_one_of except that it requires exactly one of the features to be selected.
  • none_or_one_of
    This macro allows you to specify that certain features are mutually exclusive. It generates any combination of the selected features, by the combination formula: n!/(2!*(n - 2)!), where n is the number of features. For example, if you have 5 features, you will get 5!/(3!*2!) which is 10 combinations or for 10 features, you will get 10!/(8!*2!) which is 45 combinations
