Unfortunately, (R) and (W) are valid markups for enumerated lists, as described at: https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#enumerated-lists So, we ned to replace them by: (R) -> (Read) (W) -> (Write) As otherwise, (R) will be displayed as R., with is not what it is desired. There's no need to touch (RO) and (RW).
