+ * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
+ * comprehension expression. `ngOptions` should be used when the `<select>` model needs to be bound
+ *  to a non-string value. This is because an option element can only be bound to string values at
+ * present.
+ *
+ * When an item in the `<select>` menu is selected, the array element or object property
+ * represented by the selected option will be bound to the model identified by the `ngModel`
+ * directive.
+ *
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
+ * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
+ * option. See example below for demonstration.
+ *
+ * ## Complex Models (objects or collections)
+ *
+ * **Note:** By default, `ngModel` watches the model by reference, not value. This is important when
+ * binding any input directive to a model that is an object or a collection.
+ *
+ * Since this is a common situation for `ngOptions` the directive additionally watches the model using
+ * `$watchCollection` when the select has the `multiple` attribute or when there is a `track by` clause in
+ * the options expression. This allows ngOptions to trigger a re-rendering of the options even if the actual
+ * object/collection has not changed identity but only a property on the object or an item in the collection
+ * changes.
+ *
+ * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
+ * if the model is an array). This means that changing a property deeper inside the object/collection that the
+ * first level will not trigger a re-rendering.
+ *
+ *
+ * ## `select` **`as`**
+ *
+ * Using `select` **`as`** will bind the result of the `select` expression to the model, but
+ * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
+ * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
+ * is used, the result of that expression will be set as the value of the `option` and `select` elements.
+ *
+ *
+ * ### `select` **`as`** and **`track by`**
+ *
+ * <div class="alert alert-warning">
+ * Do not use `select` **`as`** and **`track by`** in the same expression. They are not designed to work together.
+ * </div>
+ *
+ * Consider the following example:
+ *
+ * ```html
+ * <select ng-options="item.subItem as item.label for item in values track by item.id" ng-model="selected">
+ * ```
+ *
+ * ```js
+ * $scope.values = [{
+ *   id: 1,
+ *   label: 'aLabel',
+ *   subItem: { name: 'aSubItem' }
+ * }, {
+ *   id: 2,
+ *   label: 'bLabel',
+ *   subItem: { name: 'bSubItem' }
+ * }];
+ *
+ * $scope.selected = { name: 'aSubItem' };
+ * ```
+ *
+ * With the purpose of preserving the selection, the **`track by`** expression is always applied to the element
+ * of the data source (to `item` in this example). To calculate whether an element is selected, we do the
+ * following:
+ *
+ * 1. Apply **`track by`** to the elements in the array. In the example: `[1, 2]`
+ * 2. Apply **`track by`** to the already selected value in `ngModel`.
+ *    In the example: this is not possible as **`track by`** refers to `item.id`, but the selected
+ *    value from `ngModel` is `{name: 'aSubItem'}`, so the **`track by`** expression is applied to
+ *    a wrong object, the selected element can't be found, `<select>` is always reset to the "not
+ *    selected" option.
+ *
+ *
+ * @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=} required The control is considered valid only if value is entered.
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+ *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+ *    `required` when you want to data-bind to the `required` attribute.
+ * @param {comprehension_expression=} ngOptions in one of the following forms:
+ *
+ *   * for array data sources:
+ *     * `label` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
+ *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
+ *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array`
+ *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
+ *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
+ *     * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`
+ *        (for including a filter with `track by`)
+ *   * for object data sources:
+ *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ *     * `label` **`disable when`** `disable` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`group by`** `group`
+ *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`disable when`** `disable`
+ *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ *
+ * Where:
+ *
+ *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
+ *   * `value`: local variable which will refer to each item in the `array` or each property value
+ *      of `object` during iteration.
+ *   * `key`: local variable which will refer to a property name in `object` during iteration.
+ *   * `label`: The result of this expression will be the label for `<option>` element. The
+ *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
+ *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
+ *      element. If not specified, `select` expression will default to `value`.
+ *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
+ *      DOM element.
+ *   * `disable`: The result of this expression will be used to disable the rendered `<option>`
+ *      element. Return `true` to disable.
+ *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
+ *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
+ *     `value` variable (e.g. `value.propertyName`). With this the selection is preserved
+ *      even when the options are recreated (e.g. reloaded from the server).

+ * # Tracking and Duplicates
+ *
+ * When the contents of the collection change, `ngRepeat` makes the corresponding changes to the DOM:
+ *
+ * * When an item is added, a new instance of the template is added to the DOM.
+ * * When an item is removed, its template instance is removed from the DOM.
+ * * When items are reordered, their respective templates are reordered in the DOM.
+ *
+ * By default, `ngRepeat` does not allow duplicate items in arrays. This is because when
+ * there are duplicates, it is not possible to maintain a one-to-one mapping between collection
+ * items and DOM elements.
+ *
+ * If you do need to repeat duplicate items, you can substitute the default tracking behavior
+ * with your own using the `track by` expression.
+ *
+ * For example, you may track items by the index of each item in the collection, using the
+ * special scope property `$index`:
+ * ```html
+ *    <div ng-repeat="n in [42, 42, 43, 43] track by $index">
+ *      {{n}}
+ *    </div>
+ * ```
+ *
+ * You may use arbitrary expressions in `track by`, including references to custom functions
+ * on the scope:
+ * ```html
+ *    <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
+ *      {{n}}
+ *    </div>
+ * ```
+ *
+ * If you are working with objects that have an identifier property, you can track
+ * by the identifier instead of the whole object. Should you reload your data later, `ngRepeat`
+ * will not have to rebuild the DOM elements for items it has already rendered, even if the
+ * JavaScript objects in the collection have been substituted for new ones:
+ * ```html
+ *    <div ng-repeat="model in collection track by model.id">
+ *      {{model.name}}
+ *    </div>
+ * ```
+ *
+ * When no `track by` expression is provided, it is equivalent to tracking by the built-in
+ * `$id` function, which tracks items by their identity:
+ * ```html
+ *    <div ng-repeat="obj in collection track by $id(obj)">
+ *      {{obj.prop}}
+ *    </div>
+ * ```
+ *
+ * <div class="alert alert-warning">
+ * **Note:** `track by` must always be the last expression:
+ * </div>

+ *     {{model.name}}

- * # `ngOptions`
- *
- * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
- * elements for the `<select>` element using the array or object obtained by evaluating the
- * `ngOptions` comprehension expression.
- *
- * In many cases, `ngRepeat` can be used on `<option>` elements instead of `ngOptions` to achieve a

+ * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits such as reducing
+ * memory and increasing speed by not creating a new scope for each repeated instance, as well as providing
  * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
- * comprehension expression. `ngOptions` should be used when the `<select>` model needs to be bound
- *  to a non-string value. This is because an option element can only be bound to string values at
- * present.
+ * comprehension expression.
  *
  * When an item in the `<select>` menu is selected, the array element or object property
  * represented by the selected option will be bound to the model identified by the `ngModel`
  * directive.
  *
+ * If the viewValue contains a value that doesn't match any of the options then the control
+ * will automatically add an "unknown" option, which it then removes when this is resolved.
+ *
  * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
  * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
  * option. See example below for demonstration.
  *
- * <div class="alert alert-warning">
- * **Note:** `ngModel` compares by reference, not value. This is important when binding to an
- * array of objects. See an example [in this jsfiddle](http://jsfiddle.net/qWzTb/).
- * </div>
- *
- * ## `select` **`as`**
- *
- * Using `select` **`as`** will bind the result of the `select` expression to the model, but
- * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
- * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
- * is used, the result of that expression will be set as the value of the `option` and `select` elements.
- *
- *
- * ### `select` **`as`** and **`track by`**
- *
- * <div class="alert alert-warning">
- * Do not use `select` **`as`** and **`track by`** in the same expression. They are not designed to work together.
+ * <div class="alert alert-info">
+ * The value of a `select` directive used without `ngOptions` is always a string.
+ * When the model needs to be bound to a non-string value, you must either explictly convert it
+ * using a directive (see example below) or use `ngOptions` to specify the set of options.
+ * This is because an option element can only be bound to string values at present.
  * </div>
  *
- * Consider the following example:
- *
- * ```html
- * <select ng-options="item.subItem as item.label for item in values track by item.id" ng-model="selected">
- * ```
- *
- * ```js
- * $scope.values = [{
- *   id: 1,
- *   label: 'aLabel',
- *   subItem: { name: 'aSubItem' }
- * }, {
- *   id: 2,
- *   label: 'bLabel',
- *   subItem: { name: 'bSubItem' }
- * }];
- *
- * $scope.selected = { name: 'aSubItem' };
- * ```
- *
- * With the purpose of preserving the selection, the **`track by`** expression is always applied to the element
- * of the data source (to `item` in this example). To calculate whether an element is selected, we do the
- * following:
- *
- * 1. Apply **`track by`** to the elements in the array. In the example: `[1, 2]`
- * 2. Apply **`track by`** to the already selected value in `ngModel`.
- *    In the example: this is not possible as **`track by`** refers to `item.id`, but the selected
- *    value from `ngModel` is `{name: 'aSubItem'}`, so the **`track by`** expression is applied to
- *    a wrong object, the selected element can't be found, `<select>` is always reset to the "not
- *    selected" option.
- *
- *
- * @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=} required The control is considered valid only if value is entered.
- * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
- *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
- *    `required` when you want to data-bind to the `required` attribute.
- * @param {comprehension_expression=} ngOptions in one of the following forms:
+ * ### Example (binding `select` to a non-string value)
  *
- *   * for array data sources:
- *     * `label` **`for`** `value` **`in`** `array`
- *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
- *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
- *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
- *     * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`
- *        (for including a filter with `track by`)
- *   * for object data sources:
- *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
- *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`group by`** `group`
- *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
- *
- * Where:
- *
- *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
- *   * `value`: local variable which will refer to each item in the `array` or each property value
- *      of `object` during iteration.
- *   * `key`: local variable which will refer to a property name in `object` during iteration.
- *   * `label`: The result of this expression will be the label for `<option>` element. The
- *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
- *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
- *      element. If not specified, `select` expression will default to `value`.
- *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
- *      DOM element.
- *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
- *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
- *     `value` variable (e.g. `value.propertyName`). With this the selection is preserved
- *      even when the options are recreated (e.g. reloaded from the server).
