+   * Native range input with validation and transformation. Sets the `number` validation
+   * to always have a valid number. Note that IE9 does not support the `range` type, but falls back
+   * to a text input. Model binding, validation and number parsing are nevertheless supported.
    *
    * @param {string} ngModel Assignable angular expression to data-bind to.
    * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} min Sets the `min` validation to ensure that the value entered is greater the `min`.
-   * @param {string=} max Sets the `max` validation to ensure that the value entered is lesser than `max`.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the value does not match the
-   *    RegExp pattern expression. Expected value is `/regexp/` for inline patterns or `regexp` for
-   *    patterns defined as scope expressions.
-   * @param {string=} ngChange Angular expression to be executed when input changes due to user
-   *    interaction with the input element.
+   * @param {string=} min Sets the `min` validation to ensure that the value entered is greater
+   *                  than `min`. Can be interpolated.
+   * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`.
+   *                  Can be interpolated.
+   * @param {string=} ngMin Takes an expression. Sets the `min` validation to ensure that the value
+   *                  entered is greater than `min`. Does not set the `min` attribute and therefore
+   *                  adds no native HTML5 validation.
+   * @param {string=} ngMax Takes an expression. Sets the `max` validation to ensure that the value
+   *                  entered is less than `max`. Does not set the `min` attribute and therefore
+   *                  adds no native HTML5 validation.
+   * @param {string=} ngChange Angular expression to be executed when the ngModel value changes due
+   *                  to user interaction with the input element.
