Description

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

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

Processing expectations

Formatted as a displayed block. Often outputs the generated text Caution 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.
