- * @ngdoc module
- * @name ngAria
- * @description
- *
- * The `ngAria` module provides support for common
- * [<abbr title="Accessible Rich Internet Applications">ARIA</abbr>](http://www.w3.org/TR/wai-aria/)
- * attributes that convey state or semantic information about the application for users
- * of assistive technologies, such as screen readers.
- *
- * <div doc-module-components="ngAria"></div>
- *
- * ## Usage
- *
- * For ngAria to do its magic, simply include the module `ngAria` as a dependency. The following
- * directives are supported:
- * `ngModel`, `ngChecked`, `ngRequired`, `ngValue`, `ngDisabled`, `ngShow`, `ngHide`, `ngClick`,
- * `ngDblClick`, and `ngMessages`.
- *
- * Below is a more detailed breakdown of the attributes handled by ngAria:
- *
- * | Directive | Supported Attributes |
- * |---------------------------------------------|----------------------------------------------------------------------------------------|
- * | {@link ng.directive:ngModel ngModel} | aria-checked, aria-valuemin, aria-valuemax, aria-valuenow, aria-invalid, aria-required, input roles |
- * | {@link ng.directive:ngDisabled ngDisabled} | aria-disabled |
- * | {@link ng.directive:ngRequired ngRequired} | aria-required |
- * | {@link ng.directive:ngChecked ngChecked} | aria-checked |
- * | {@link ng.directive:ngValue ngValue} | aria-checked |
- * | {@link ng.directive:ngShow ngShow} | aria-hidden |
- * | {@link ng.directive:ngHide ngHide} | aria-hidden |
- * | {@link ng.directive:ngDblclick ngDblclick} | tabindex |
- * | {@link module:ngMessages ngMessages} | aria-live |
- * | {@link ng.directive:ngClick ngClick} | tabindex, keypress event, button role |
- *
- * Find out more information about each directive by reading the
- * {@link guide/accessibility ngAria Developer Guide}.
- *
- * ##Example
- * Using ngDisabled with ngAria:
- * ```html
- * <md-checkbox ng-disabled="disabled">
- * ```
- * Becomes:
- * ```html
- * <md-checkbox ng-disabled="disabled" aria-disabled="true">
- * ```
- *
- * ##Disabling Attributes
- * It's possible to disable individual attributes added by ngAria with the
- * {@link ngAria.$ariaProvider#config config} method. For more details, see the
- * {@link guide/accessibility Developer Guide}.

- * @name $aria
- *
- * @description
- * @priority 200
- *
- * The $aria service contains helper methods for applying common
- * [ARIA](http://www.w3.org/TR/wai-aria/) attributes to HTML directives.
- *
- * ngAria injects common accessibility attributes that tell assistive technologies when HTML
- * elements are enabled, selected, hidden, and more. To see how this is performed with ngAria,
- * let's review a code snippet from ngAria itself:
- *
- *```js
- * ngAriaModule.directive('ngDisabled', ['$aria', function($aria) {
- * return $aria.$$watchExpr('ngDisabled', 'aria-disabled', nodeBlackList, false);
- * }])
- *```
- * Shown above, the ngAria module creates a directive with the same signature as the
- * traditional `ng-disabled` directive. But this ngAria version is dedicated to
- * solely managing accessibility attributes on custom elements. The internal `$aria` service is
- * used to watch the boolean attribute `ngDisabled`. If it has not been explicitly set by the
- * developer, `aria-disabled` is injected as an attribute with its value synchronized to the
- * value in `ngDisabled`.
- *
- * Because ngAria hooks into the `ng-disabled` directive, developers do not have to do
- * anything to enable this feature. The `aria-disabled` attribute is automatically managed
- * simply as a silent side-effect of using `ng-disabled` with the ngAria module.
- *
- * The full list of directives that interface with ngAria:
- * * **ngModel**
- * * **ngChecked**
- * * **ngRequired**
- * * **ngDisabled**
- * * **ngValue**
- * * **ngShow**
- * * **ngHide**
- * * **ngClick**
- * * **ngDblclick**
- * * **ngMessages**
- *
- * Read the {@link guide/accessibility ngAria Developer Guide} for a thorough explanation of each
- * directive.
- *
- *
- * ## Dependencies
- * Requires the {@link ngAria} module to be installed.
