## 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 `LiteralLayout`s. 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.

### Future Changes

The `xml:space` attribute is automatically provided in the XML DTD.

### Parents

## 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 `LiteralLayout`s. All white space and line breaks must be preserved.

linenumbering

  Line numbering indicates whether or not the lines of a `LiteralLayout` are to be automatically numbered. The details of numbering (every line or only selected lines, on the left or right, etc.) are left up to the processing application. Be aware that not all processors are capable of numbering lines.

width

  `Width` specifies the width (in characters) of the longest line in this `LiteralLayout` (formatters may use this value to determine scaling or rotation).

## See Also

`computeroutput`, `lineannotation`, `programlisting`, `screen`, `screenshot`, `synopsis`, `userinput`.
