48//  Token would map to a list like Ted proposed. The utility has no idea what

50//  ErrorStatus - Level of Error or success. Independent of Token. If you
51//      don't know the token you will at least know pass or fail.
52//  String - Optional extra information about the error. Could be used for
53//      debug or future expansion
54//
55//  Attributes - Options screen attributes for String. Could allow the string to be different colors.
