    // 外部リンクは特筆することはありません。
    add(new ExternalLink("external", "http://irof.hateblo.jp/"));
    // ajax なリンク
    // AjaxRequestTarget で一部を書き換えるのが普通の使い方

    // ファイルを直接ダウンロードさせるリンク
    // ファイルじゃなかったら ResourceLink を使う感じかな。

    // 任意のリソースをへのリンク
    // ResourceLink 自体はたいしたことなくて、 ResourceReference が主役ぽい。
