How to translate Trac custom content added with site.html?

We have customized our Trac instance to display additional content to the newticket page, with the following site.html file (as explained in documentation):

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:py="http://genshi.edgewall.org/"
      py:strip="">
    <form py:match="div[@id='content' and @class='ticket']/form[@action='/newticket#ticket']" py:attrs="select('@*')">
      <div class="warning">
        <p>You are about to create a new JOSM ticket.
        </p>
        <p>Please make sure to always use this link in <a href="wiki/Help/Action/About">About Dialog</a> (Shift-F1) to come here:</p>
        <img src="raw-attachment/wiki/Help/Action/About/bugreport_small.png" alt="Bug report link in About dialog" height="53" width="361" />
        <p>Clicking on this link prefills the bug report with useful information for us (<a href="wiki/Help/Action/ShowStatusReport">Status Report</a>).
        </p>
        <p>In any case, don't be shy :) Please let us a way to contact you if needed (either by <a href="register">creating an account</a> or entering your e-mail address below (it won't be publicly visible but will allow us to reach you, and you will be notified about ticket progress).
        </p>
      </div>
      ${select('*')}
    </form>
</html>

I don't see anything in the documentation about translation. How can we translate this text now?

Unfortunately this is not easy until something like the proposal for custom labels has been realized.

Currently it requires adding your additional msgids to Trac core PO files and recompiling and installing that custom Trac version - quite ugly and not remotely as modifiable as the template.

Providing custom translations within a plugin would not be effective, because plugin translations would reside in a translation domain, that is not evaluated for Trac core templates like the (new) ticket page.

I have finally come up with a small JavaScript solution.

It's simple when you only need a few languages with a text that doesn't change:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:py="http://genshi.edgewall.org/"
      py:strip="">
    <form py:match="div[@id='content' and @class='ticket']/form[@action='/newticket#ticket']" py:attrs="select('@*')">
      <div class="warning">
        <table style="border:0; border-collapse:separate; border-spacing:0 10px" class="wiki">
        <tr><td style="background:#FFFC75; border:1px solid #ccc; border-right:0" valign="top">
        <p id="josm_warning_01">You are about to create a new JOSM ticket.
        </p>
        <p id="josm_warning_02">Please make sure to always use <a href="wiki/Help/Action/ReportBug">Help/Report bug</a> or this link in <a href="wiki/Help/Action/About">About Dialog</a> (Shift-F1) to come here:</p>
        <img src="raw-attachment/wiki/Help/Action/ReportBug/reportbug.png" alt="Bug report menu entry" height="84" width="207" />
        <img src="raw-attachment/wiki/Help/Action/About/bugreport_small.png" alt="Bug report link in About dialog" height="53" width="361" />
        </td></tr>
        </table>
      </div>
      <script type="text/javascript">

if (navigator.language.indexOf('fr') == 0) {
  document.getElementById("josm_warning_01").innerHTML = 'Vous êtes sur le point de créer un nouveau ticket JOSM.';
  document.getElementById("josm_warning_02").innerHTML = 'S\'il vous plaît, assurez-vous de toujours utiliser <a href="wiki/Help/Action/ReportBug">Aide/Rapporter un bug</a> ou ce lien dans la <a href="wiki/Help/Action/About">fenêtre À propos</a> (Shift-F1) pour venir ici:';

} else if (navigator.language.indexOf('de') == 0) {
  document.getElementById("josm_warning_01").innerHTML = 'Sie sind dabei, ein neues JOSM-Ticket zu erstellen.';
  document.getElementById("josm_warning_02").innerHTML = 'Bitte nutzen Sie immer <a href="wiki/De:Help/Action/ReportBug">Hilfe → Fehler melden</a> oder diesen Link im <a href="wiki/De:Help/Action/About">"Über JOSM..."-Fenster</a>, um hierher zu gelangen:';
}
      </script>
      ${select('*')}
    </form>
</html>
