What is it?
The Listing element displays all characters "As-Is" in the browser as a fixed-width font. Recommended display of this element is a 132 character line length. Until a closing LISTING tag is encountered, other HTML elements are displayed on screen as text and not evaluated.

The rules for this sort of behavior can have many consequences in parsing techniques, thus the use of this element is strongly discouraged (the Pre element should be used instead.) This element is no longer standard HTML. It is considered "obsolete" in the HTML 2.0 , 3.0 and 3.2 specifications, and is not mentioned in HTML 4.0 and beyond. It may be implemented by browsers for backward compatibility.

SDA also allows attributes and values from the original element to be used in the new SDA element where necessary.
Value: Lit (Denotes 'literal or computer text' in SDA.)
