How can ngdoc be used to document a function declaration in an angular service?

Question

I would like to add ngdoc documentation to a function declaration within an angular service. How can I do this for myFunction in the example below?

I reckon I need something like @closure, @functionOf or @functionIn.

Please note that (in contrast to myMethod) myFunction is not a method.

/**
 * @ngdoc service
 * @name myApp.service:myService
 * @description
 *   My application.
 */
angular
  .module('myApp')
  .factory('myService', function() {
    'use strict';

    var x = 0;

    /**
     * @ngdoc function
     * @name ?
     * @description
     *   How can this be identified as being within the closure of 
     *   myService, and not be described as a constructor?
     */
    function myFunction (z) {
      x++;
      x += z;
    }

    return {
      /**
       * @ngdoc method
       * @name myMethod
       * @methodOf myApp.service:myService
       * @description
       *   A method of myService.
       */
      myMethod : function (x) {
        myFunction(x);
      }
    };
  })

The keyname you are looking for is the @methodOf annotation. When i'm writing documentation using grunt-ngdocs for a service it ends up looking like the following:

/**
  * @ngdoc overview
  * @name module
  * @description A small module containing stuff
  */
angular
  .module(module, [])
  .factory('name', factory);

/**
  * @ngdoc object
  * @name module.name
  * @description Its a pretty bad factory
  */
function factory() {
  return {
    doSomething: doSomething
  };

  /**
    * @ngdoc function
    * @name module.name#doSomething
    * @methodOf module.name
    * @description Does the thing
    * @param {string=} [foo='bar'] This is a parameter that does nothing, it is
                                   optional and defaults to 'bar'
    * @returns {undefined} It doesn't return
    */
  function doSomething(foo){...}
}
