/**
* @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.
*
* ## Usage
*
* For ngAria to do its magic, simply include the module `ngAria` as a dependency. The following
* directives are supported:
* `ngModel`, `ngChecked`, `ngReadonly`, `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:ngReadonly ngReadonly} | aria-readonly |
* | {@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, keydown 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 Specific Attributes
* It is 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}.
*
* ## Disabling `ngAria` on Specific Elements
* It is possible to make `ngAria` ignore a specific element, by adding the `ng-aria-disable`
* attribute on it. Note that only the element itself (and not its child elements) will be ignored.

/**
* @ngdoc service
* @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**
* * **ngReadonly**
* * **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.
