Description

A Literal is some specific piece of data, taken literally, from a computer system. It is similar in some ways to UserInput and ComputerOutput, but is somewhat more of a general classification. The sorts of things that constitute literals varies by domain.

Processing expectations

Formatted inline. A literal is frequently distinguished typographically and Literal is often used wherever that typographic presentation is desired.

The MoreInfo attribute can help generate a link or query to retrieve additional information.

 Future Changes

The content model of Literal will be constrained to (#PCDATA | Replaceable | InlineGraphic) in DocBook V4.0.
