revision:
The <legend> tag defines a caption for the <fieldset> element. The <legend> element is used to add a caption to a group of related form <input> elements that have been grouped together into a <fieldset>.
It provides titles for form sections, providing a nice alternative to the "headline" elements. The titles are designed to be used with the "fieldset" element, and (strictly speaking) should only be used inside of one. Organizing form fields into "fieldset" groups, with appropriate "legend" captions can help make complicated forms more attractive and easier to use.
