  orderedBy: {short: What order the list has, comments: 'Applications SHOULD render ordered lists in the order provided, but MAY allow users to re-order based on their own preferences as well.

  emptyReason: {short: Why list is empty, comments: 'The various reasons for an empty list make a significant interpretation to its interpretation.
