You're actually wrong. (1) "A JSON text ... conforms to the JSON value grammar." (2) The entire standard for the object grammar is, "An object structure is represented as a pair of curly bracket tokens surrounding zero or more name/value pairs. A name is a string. A single colon token follows each name, separating the name from the value. A single comma token separates a value from a following name." In other words, people SHOULD ignore both of those, because ignoring both of those is a part of the ECMA-404 JSON standard. (The latter actually wasn't even a part of RFC 4627; the operative word there was SHOULD, not MUST.)
