//  Token would map to a list like Ted proposed. The utility has no idea what 
//      happens on the other side.
//  ErrorStatus - Level of Error or success. Independent of Token. If you 
//      don't know the token you will at least know pass or fail.
//  String - Optional extra information about the error. Could be used for 
//      debug or future expansion
//
//  Attributes - Options screen attributes for String. Could allow the string to be different colors.
