Isn't it? The "Overview" section doesn't read like standard English at all. I thought it may be ACE

It's not. Take this sentence: "ACE construction rules require that each noun be introduced by a determiner (a, every, no, some, at least 5, ...)."

The sentence does not follow the rule it describes, since "rules" does not have a determiner. It might be worth a try, but I suspect ACE would make the article awkward and harder to read.
