Edit: The manual says they are independent symbols.
"Type Independent: There are only 2 markers in this type, as in type VX. Breath phonemes are built in this type. Do not forget to fill in the symbols in the independent symbol list. For details please refer to “br1,br2,br3,br4,br5” in the test project."
