+     * @param sources an Array, Dictionary, or Object containing sources as values, or a single
+     * source value. The sources may be Strings (representing urls), URLRequests, ByteArrays,
+     * or a Class that can be instantiated to become a URLRequest or ByteArray. Note that
+     * the format of your sources Object dictates the format of the return Object.
+     * @param completeCallback the function to call when complete. The signature should be:
+     * <code>function (value :Object) :void</code>. Note that the structure of the return Object
+     * is dictated by the sources parameter. If you pass in an Array, you get your results
+     * in an Array. If you use a Dictionary or Object, the results will be returned as the same,
+     * with the same keys used in sources now pointing to the results. If your sources parameter
+     * was just a single source (like a String) then the result will just be a single result,
+     * like a DisplayObject. Each result will be a DisplayObject or an Error
+     * describing the problem.
+     * @param forEach if true, each value or error will be returned as soon as possible. The values
+     * or errors will be returned directly to the completeCallback. Any keys are lost, so you
+     * probably only want to use this with an Array sources.
+     * @param appDom the ApplicationDomain in which to load the contents, or null to specify
+     * that it should load in a child of the current ApplicationDomain.
