Certain features are not overridden when phones consist of base characters and diacritics having mutually exclusive features.
For example, you must modify the features of the phone [d̥], because Phonology Assistant allows it to have the mutually exclusive features +voice and -voice (the base character has the feature +voice and the diacritic has the feature -voice).
