boolean

The <boolean> element is used to express one of two opposite values, such as yes or no, on or off, true or false, high or low, and so forth. The element itself is empty; the value of the element is stored in its state attribute, and the semantic associated with the value is typically in a specialized name derived from this element. If you need more than two values (for example, "yes," "no" and "don't care") use the <state> element instead. This element is primarily for specialization, where it can be used to require a logical true or false designation in a particular part of the document.

OASIS TC Note: This element is deprecated. It is functionally equivalent to <state value="yes|no"/>, which is recommended as its replacement in all cases.
