objects:
  MessageData:
    description: >
      An object to describe a message. It uses human
      readable strings to describe the triggers, action and
      style of the message as well as the text of the message
      and call to action.
    fields:
      action:
        type: ActionName
        description: >
          A URL of a page or a deeplink.
          This may have substitution variables in.

          A string map containing query parameters that will be appended to the action URL.
          This is useful for opening URLs in tabs, or specifying that the tab should be private.

          "private": "true".

          The params and their values are all determined downstream of the messaging component, by
          the embedding app's deeplink processing machinery.
