-/**
- * Allows adding and removing the boolean attributes from the element.
- *
- * Using `<button disabled="{{false}}">` does not work since it would result
- * in `<button disabled="false">` rather than `<button>`.
- * Browsers change behavior based on presence/absence of attribute rather the
- * its value.
- *
- * For this reason we provide alternate `ng-`attribute directives to
- * add/remove boolean attributes such as `<button ng-disabled="{{false}}">`
- * which will result in proper removal of the attribute.
- *
- * The full list of supported attributes are:
- *
- *  - [ng-checked]
- *  - [ng-disabled]
- *  - [ng-multiple]
- *  - [ng-open]
- *  - [ng-readonly]
- *  - [ng-required]
- *  - [ng-selected]

-/**
- * In browser some attributes have network side-effect. If the attribute
- * has `{{interpolation}}` in it it may cause browser to fetch bogus URLs.
- *
- * Example: In `<img src="{{username}}.png">` the browser will fetch the image
- * `http://server/{{username}}.png` before Angular has a chance to replace the
- * attribute with data-bound url.
- *
- * For this reason we provide `ng-`prefixed attributes which avoid the issues
- * mentioned above as in this example: `<img ng-src="{{username}}.png">`.
- *
- * The full list of supported attributes are:
- *
- * - [ng-href]
- * - [ng-src]
- * - [ng-srcset]
