BASIC_ELEMENT is an optional toggle that if checked, the element is made up by a list of [pay components|PAY COMPONENTS] only, and is considered a basic element. If the toggle is not checked, the element may be made up by a list of [pay components|PAY COMPONENTS] and also refers to another element (also known as an element mapping). This type of element is known as a compound element. By mapping one element to another it is possible to greatly reduce the amount of [pay component|PAY COMPONENTS] keying that is required to set-up all of the required elements.
