indeed but we are not discussing this issue or put this "equivalence" under questioning (in fact this is reproduced in the signal type 6 definition) the RFC took as logic (control plane) to set the RCC value when the notation of the signal included a "c" we could have created yet another exception but we did not - for several reasons -
