There are <> characters, which are awkward on a good day. Yeah, we use them in HTML but the editor helps with that. And there are a bunch of special characters and "objects" that require interpretation. JSON has what? Quotes, square brackets, colons, and commas, used the way they are used in most programming languages, and thus familiar to most of us. Outside of terseness, which is overrated, what real advantages does XENON provide?
