Description
LiteralLayout is a verbatim environment. Unlike the other verbatim environments, it does not have strong semantic overtones and may not imply a font change.
Processing expectations
This element is displayed "verbatim"; whitespace and linebreaks within this element are significant.
Unlike ProgramListing and Screen, which usually imply a font change, LiteralLayout does not. How spaces are to be represented faithfully in a proportional font is not addressed by DocBook.
In DocBook V3.1, the Class attribute was added to give users control over the font used in LiteralLayouts. If the Class attribute is specified and its value is Monospaced, then the LiteralLayout will be presented in a monospaced font, probably the same one used for other verbatim environments. The default value for Class is Normal, meaning that no font change will occur.
Future Changes
The InterfaceDefinition element will be discarded in DocBook V4.0. It will no longer be available in the content model of this element.

Attributes
- Class
Class distinguishes between literal layout environments that are presented in a monospaced font and literal layout environments that have no implicit font change.
- Format
The Format attribute applies the linespecific notation to all LiteralLayouts. All white space and line breaks must be preserved.
- Width
Width specifies the width (in characters) of the longest line in this LiteralLayout (formatters may use this value to determine scaling or rotation).
