title: Why is the file upload ignoreing the language setting?
body: <p>I have an English and German site, where the user can switch from English to German. When the user switches the site, the content is translated, the language information is set (<code>lang="en", lang="de"</code>) but file upload (<code>&lt;input type="file"&gt;</code>) is in German. Is there a way to translate it without customizing the file upload? </p>
  
  <p>Example (egnlish):</p>
  
  <pre><code>&lt;html lang="en"  xml:lang="en"&gt;
  &lt;head&gt;
      &lt;title&gt;Internationalisation test&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;form&gt;
        &lt;input type="file" name="test"&gt;
      &lt;/form&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Example (german):</p>
  
  <pre><code>&lt;html lang="de"  xml:lang="de"&gt;
  &lt;head&gt;
      &lt;title&gt;Internationalisation test&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;form&gt;
        &lt;input type="file" name="test"&gt;
      &lt;/form&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
