FieldsetLegend [rule] v1.0.0

Logically related input groups (radio buttons, checkboxes, or multi-field address blocks) must be wrapped in <fieldset> with a <legend> that names the group, so screen readers announce the group context before each option.

Rationale

Without fieldset/legend, a radio button labelled 'Yes' reads as just 'Yes, radio button'. With a legend of 'Receive marketing emails?', it reads as 'Receive marketing emails? Yes, radio button' — the user understands the question.
