The IHTMLElement5::ariaRequired property indicates which input fields of a form must be filled in before it can be submitted. If the user attempts to submit the form without the required information, you may set IHTMLElement5::ariaInvalid to indicate the error.

Note  For cross-browser compatibility, always use the WAI-ARIA attribute syntax to access and modify ARIA properties, for example object.setAttribute("aria-valuenow", newValue).
