`<boolean>`

The <boolean> element was deprecated in DITA version 1.1. It was originally intended to express one of two opposite values, such as yes / no or on / off.

Note: This element is deprecated. It is functionally equivalent to

<state
                    value="yes|no"/>

, which is recommended as its replacement in all cases.
