Is the distinction between "s" and "S" insufficient from an accessibility point of view

The nonterminal S is only used once and is never serialized so its name is irrelevant.

In the interest of accessibility, I suggest we rename it WS.

What kind of accessibility issue are we worrying about? Visual acuity (because lowercase and uppercase S are very similar)? Or screen readers? or ... ?

Since the salient difference between s and S is (or was, last time I looked) that s is for optional whitespace and S is for required whitespace, I wonder if RS ('required space') or ws-plus or something similar might be a better name than WS.

It was @LinguaCelta that raised the point that they are visually too similar. Subsequent experimentation with grammars has persuaded me that this is true irrespective of accessibility criteria.

I was trying to keep the name short, I thought WS filled the bill. I could equally go with RS. I'm a little less fond of the somewhat longer ws-plus or s-required, etc. family of choices, but if there's a consensus favorite, I won't fuss.

The group favors RS.
