<LISTING> ... </LISTING> LISTING
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 (as well as the XMP element) is
no longer standard HTML. They are considered "obsolete" in HTML specifications
beginning with 2.0, but they should be implemented by browsers for backward
compatibility.
