As we can't mark-up the labels in dictionaries (using HTML), we might need to add dir ("ltr" and "rtl") members on dictionaries that contain things that are displayed to the end-user (defaulting to "ltr" when missing). So:

[
  displayItems: [{
    label: "البند الخاص (للبيع!)",
    dir: "rtl",
    lang: "ar-AE",
    amount: { },
  }]
]

Have the i18n folks looked at this API? They will likely ask us to add that. We might also need lang.
