> JSON maps directly to language-native data structures, but XML does not. So what? It is irrelevant. In all the problems we have ever faced when creating federated chat applications on various platforms, I can't recall a single time when stream format made any difference. For example, making your messages appear in consistent order on all of your and your chat partner's devices is a real problem. The development of the efficient strategy to achieve this has nothing to do with format, yet, has a much more visible impact on user experience. In fairness, the debate of what is better suited for the protocol development, Message Sequence Charts [1] or Sequence Diagrams [2] has more sense than debating about XML vs JSON.
