It’s not terribly significant, I’m afraid. But in a pair of parenthesised Runas_Spec, e.g., (operator:operator), the one on the right represents a group name, but does not follow the syntax for group names (if you look at the definition of Runas_Member above, group names are supposed to be %group). Really, the point is that you shouldn’t take the EBNF too seriously.
The end of the article mentions that the implementation itself doesn’t follow the EBNF precisely. Would be nice to know which parts deviate.
