+     * This example is built on the following mock data:
+     * <books>
+     *         <book publisher="Addison-Wesley" name="Design Patterns" />
+     *         <book publisher="Addison-Wesley" name="The Pragmattic Programmer" />
+     *         <book publisher="Addison-Wesley" name="Test Driven Development" />
+     *         <book publisher="Addison-Wesley" name="Refactoring to Patterns" />
+     *         <book publisher="O'Reilly Media" name="The Cathedral & the Bazaar" />
+     *         <book publisher="O'Reilly Media" name="Unit Test Frameworks" />
+     *     </books>
+     * 
+     * This example was created to illustrate how one can build an synchronous
+     * TestCase - one that relies on remote data of some sort.
+     * This use case is now diminished by the creation of E4X and easily
+     * readable/editable XML data directly in source form.
+     * But asynchronous tests will probably need to be built at some point
+     * by somebody... If you're them, maybe you can use this as a template.
