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.
This element is deprecated. It is functionally equivalent to
<state value="yes|no"/>, which is recommended as its replacement in all cases.
See appendix for information about this element in OASIS document type shells.
