A recent review highlighted that the json-schema meta-schema allows any combination of if/then/else schema keywords even though if, then or else by themselves makes little sense. With an added meta-schema to only allow valid combinations, there's a handful of schemas found which need fixing in a variety of ways. Incorrect indentation is the most common issue.
