25 * with <a href="TestPage.html">your XHTML page</a>. Include there
26 * a script that will <em>boot Java</em> in your browser.
28 * Then use <code>@Page</code> annotation to
29 * generate a Java representation of elements with IDs in that page.
30 * Depending on the type of the elements, they will have different
31 * methods (e.g. <code>PG_TITLE</code> has <code>setText</code>, etc.).
32 * Use <code>@OnClick</code> annotation to associate behavior
33 * with existing elements. Use the generated elements
34 * (<code>PG_TITLE</code>, <code>PG_TEXT</code>) to modify the page.
36 * Everything is type-safe. As soon as somebody modifies the page and
37 * removes the IDs or re-assigns them to wrong elements. Java compiler
40 * Welcome to the type-safe HTML5 world!
