/**
 * <p>A factory providing each concrete role in the ARIA specification. Each role implements
 * methods that a GWT application can use to modify the appropriate DOM attributes for that
 * role.</p>
 *
 * <p>For example, suppose our GWT app has a image button and we want to make it visible in screen
 * readers as a button with some help text. To do this, we add a <i>button</i> role to the image and
 * set the ARIA <i>label</i> property to the help text that the screen reader can use:</p>
 *
 * <pre>
 *    Roles.getButtonRole().set(img.getElement());
 *    Roles.getButtonRole().setAriaLabelProperty(img.getElement(), "some help text");
 * </pre>
 *
 * <p>Most ARIA properties have a prefix of "aria-" and only affect screen readers, but there is
 * one exception: the "tabindex" property is the same one used for tab order in regular widgets.
 * For example, to set tabindex to 0 for the button:
 * </p>
 *
 * <pre>
 *   Roles.getButtonRole().setTabindexExtraAttribute(img.getElement(), 0);
 * </pre>
 *
 * <p>When the button changes state (it's enabled or disabled), we can change the ARIA enabled
 * state to match, like this:</p>
 *
 * <pre>
 *   Roles.getButtonRole().setAriaEnabledState(img.getElement(), isEnabled);
 * </pre>
 *
 * <p>ARIA distinguishes between properties (which change rarely and could be set in static HTML)
 * and states (which need to be updated in response to user input). This distinction can get a bit
 * blurry when a GWT app updates the DOM dynamically. Generally you should update ARIA
 * attributes at the same time that you change the CSS styles on a DOM node, so that a screen
 * reader will see the same state as someone viewing the page visually.</p>
 *
 * <p>The role interfaces form a hierarchy whose root is the {@link Role} interface, which contains
 * generic methods that aren't specific to a role. Some abstract roles include:</p>
 * <ol>
 * <li>{@link WidgetRole}, for DOM elements that represent either standalone or composite widgets.
 * <li>{@link CompositeRole}, for widgets that contain other widgets.</li>
 * <li>{@link StructureRole}, for DOM elements that are part of the page layout.</li>
 * <li>{@link LandmarkRole}, for DOM elements defining common regions of a page.</li>
 * <li>{@link WindowRole}, for DOM elements that define windows and dialogs.</li>
 * </ol>
 * </p>
