ARIA attributes

Hello,

To add aria attributes and other type of attributes, is the basement of javascript accessibility extensions (like the WebAccessibilizer that I am the author).

Example:

var elm = document.getElementById("input");

// to attach an aria label to that element

elm.setAttribute("aria-label", "Enter your name");

// to deactivate the checking of grammatical error in that field

elm.setAttribute("spellcheck", "false");

My thinking is yeah they can be used. For example, the aria-required attribute is used dynamically with JavaScript for better functionality.
