`<legend>` HTML field set legend element

The <legend> HTML element represents a caption for the content of its parent <fieldset>.

In customizable <select> elements, the <legend> element is allowed as a child of <optgroup>, to provide a label that is easy to target and style. This replaces any text set in the <optgroup> element's label attribute, and it has the same semantics.
