negative.code: - *String*: A String is a sequence of characters that can consist of numbers, letters, white space, and
  	special characters.
  - *Number*: A Number is an integer comprised of one or more digits (`0` through `9`). The Expression Language 
  	does not provide support for fractional numbers. When converting to numbers from Date data types, they are represented as
  	the number of milliseconds since midnight GMT on January 1, 1970.
  - *Date*: A Date is an object that holds a Date and Time. Utilizing the <<dates>> and <<type_cast>> functions this data
  	type can be converted to/from Strings and numbers. If the whole Expression Language expression is evaluated to be a
  	date then it will be converted to a String with the format: "<Day of Week> <Month> <Day of Month> <Hour>:<Minute>:<Second> <Time Zone> <Year>".
  	Also expressed as "E MMM dd HH:mm:ss z yyyy" in Java SimpleDateFormat format. For example: "Wed Dec 31 12:00:04 UTC 2016".
  - *Boolean*: A Boolean is one of either `true` or `false`.
  
  All attributes are considered to be of type String.
