/**

* Renders an HTML <input> element of type <code>checkbox</code>, populated from the specified value or the specified property of the
* bean associated with our current form. This tag is only valid when nested inside a form tag body.

* <p>
* <strong>NOTE</strong>: The underlying property value associated with this field should be of type <code>boolean</code>, and any
* <code>value</code> you specify should correspond to one of the Strings that indicate a true value ("true", "yes", or "on"). If you wish
* to utilize a set of related String values, consider using the <code>multibox</code> tag.

* <p>
* <strong>WARNING</strong>: In order to correctly recognize unchecked checkboxes, the <code>ActionForm</code> bean associated with this
* form must include a statement setting the corresponding boolean property to <code>false</code> in the <code>reset()</code> method.
