## Description

A `Warning` is an admonition, usually set off from the main text.

In some types of documentation, the semantics of admonitions are clearly defined (`Caution` might imply the possibility of harm to equipment whereas `Warning` might imply harm to a person), but DocBook makes no such assertions.

### Processing expectations

Formatted as a displayed block. Often outputs the generated text “Warning” or some other visible indication of the type of admonition, especially if a `Title` is not present. Sometimes outputs a graphical icon or other symbol as well.
