+ * **Note:** The template instance and the link instance may be different objects if the template has
+ * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+ * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+ * should be done in a linking function rather than in a compile function.
+ *
+
+ *
+ * **Note:** The compile function cannot handle directives that recursively use themselves in their
+ * own templates or compile functions. Compiling these directives results in an infinite loop and a
+ * stack overflow errors.
+ *
+ * This can be avoided by manually using $compile in the postLink function to imperatively compile
+ * a directive's template instead of relying on automatic template compilation via `template` or
+ * `templateUrl` declaration or manual compilation inside the compile function.
+ *
+ *
+ *
+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+ * e.g. does not know about the right outer scope. Please use the transclude function that is passed
+ * to the link function instead.
+ *
+
+ * A compile function can have a return value which can be either a function or an object.
+ *
+ * * returning a (post-link) function - is equivalent to registering the linking function via the
+ * `link` property of the config object when the compile function is empty.
+ *
+ * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+ * control when a linking function should be called during the linking phase. See info about
+ * pre-linking and post-linking functions below.
+ *
+ *
+ * #### `link`
+ * This property is used only if the `compile` property is not defined.
+ *
+ * ```js
+ * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+ * ```
+ *
+ * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+ * executed after the template has been cloned. This is where most of the directive logic will be
+ * put.
+ *
+ * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
+ * directive for registering {@link ng.$rootScope.Scope#$watch watches}.
+ *
+ * * `iElement` - instance element - The element where the directive is to be used. It is safe to
+ * manipulate the children of the element only in `postLink` function since the children have
+ * already been linked.
+ *
+ * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+ * between all directive linking functions.
+ *
+ * * `controller` - the directive's required controller instance(s) - Instances are shared
+ * among all directives, which allows the directives to use the controllers as a communication
+ * channel. The exact value depends on the directive's `require` property:
+ * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
+ * * `string`: the controller instance
+ * * `array`: array of controller instances
+ *
+ * If a required controller cannot be found, and it is optional, the instance is `null`,
+ * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
+ *
+ * Note that you can also require the directive's own controller - it will be made available like
+ * like any other controller.
+ *
+ * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+ * This is the same as the `$transclude`
+ * parameter of directive controllers, see there for details.
+ * `function([scope], cloneLinkingFn, futureParentElement)`.
+ *
+ * #### Pre-linking function
+ *
+ * Executed before the child elements are linked. Not safe to do DOM transformation since the
+ * compiler linking function will fail to locate the correct elements for linking.
+ *
+ * #### Post-linking function
+ *
+ * Executed after the child elements are linked.
+ *
+ * Note that child elements that contain `templateUrl` directives will not have been compiled
+ * and linked since they are waiting for their template to load asynchronously and their own
+ * compilation and linking has been suspended until that occurs.
+ *
+ * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
+ * for their async templates to be resolved.
+ *
+ *
+ * ### Transclusion
+ *
+ * Transclusion is the process of extracting a collection of DOM element from one part of the DOM and
+ * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
+ * scope from where they were taken.
+ *
+ * Transclusion is used (often with {@link ngTransclude}) to insert the
+ * original contents of a directive's element into a specified place in the template of the directive.
+ * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
+ * content has access to the properties on the scope from which it was taken, even if the directive
+ * has isolated scope.
+ * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
+ *
+ * This makes it possible for the widget to have private state for its template, while the transcluded
+ * content has access to its originating scope.
+ *
+ *
+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the
+ * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
+ * Testing Transclusion Directives}.
+ *
+ *
+ * #### Transclusion Functions
+ *
+ * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
+ * function** to the directive's `link` function and `controller`. This transclusion function is a special
+ * **linking function** that will return the compiled contents linked to a new transclusion scope.
+ *
+ *
+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
+ * ngTransclude will deal with it for us.
+ *
+ *
+ * If you want to manually control the insertion and removal of the transcluded content in your directive
+ * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
+ * object that contains the compiled DOM, which is linked to the correct transclusion scope.
+ *
+ * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
+ * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
+ * content and the `scope` is the newly created transclusion scope, to which the clone is bound.
+ *
+ *
+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a translude function
+ * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
+ *
+ *
+ * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
+ * attach function**:
+ *
+ * ```js
+ * var transcludedContent, transclusionScope;
+ *
+ * $transclude(function(clone, scope) {
+ * element.append(clone);
+ * transcludedContent = clone;
+ * transclusionScope = scope;
+ * });
+ * ```
+ *
+ * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
+ * associated transclusion scope:
+ *
+ * ```js
+ * transcludedContent.remove();
+ * transclusionScope.$destroy();
+ * ```
+ *
+ *
+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
+ * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
+ * then you are also responsible for calling `$destroy` on the transclusion scope.
+ *
+ *
+ * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
+ * automatically destroy their transluded clones as necessary so you do not need to worry about this if
+ * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
+ *
+ *
+ * #### Transclusion Scopes
+ *
+ * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
+ * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
+ * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
+ * was taken.
+ *
+ * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
+ * like this:
+ *
+ * ```html
+ *
+ * **Note**: Typically directives are registered with `module.directive`. The example below is
+ * to illustrate how `$compile` works.
+ *
+ *
+
+ * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
+ * e.g. will not use the right outer scope. Please pass the transclude function as a
+ * `parentBoundTranscludeFn` to the link function instead.
+ *
+ *
+ * @param {number} maxPriority only apply directives lower than given priority (Only effects the
+ * root element(s), not their children)
+ * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
+ * (a DOM element/tree) to a scope. Where:
+ *
+ * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+ * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ * `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ * called as:
+ forEach($compileNodes, function(node, index) {
