Btw the standard uses a modified EBNF to describe the productions. That’s explained in the first part of the standard. Everything cascades in the standard, so you really need to commit to reading the whole standard, not the Wikipedia article. It’s a pain, but I’ve found it useful to do so. But then I’ve been a computer geek for 48 years, and this type of stuff is what I get paid to do. So nitpicking is my job.
