put this in my zope.schema-derived interface, and then have proper
translations, having u'foo_label' as the key to use in my .pot file
(see below). Will give this a try...

I'm not sure that I understand this part, but I'll dig Philipp's book a
bit more.

Hmmm... so far, I was only aware of doing things like this, in page
templates:

<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en"
  xmlns:tal="http://xml.zope.org/namespaces/tal";
    xmlns:metal="http://xml.zope.org/namespaces/metal";
      xmlns:i18n="http://xml.zope.org/namespaces/i18n";
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        lang="en" metal:use-macro="context/main_template/macros/master"
            i18n:domain="some.product">

<a tal:attributes="href string:${area/id}/@@details"
  i18n:translate="area_details" class="imglink">
  <img src="#" tal:attributes="src 
string:/${context/virtual_url_path}/++resource++some.product.images/magnifier.gif"
       alt="Area Details" title="Area Details" i18n:translate="alt title" />


I then have a locale.pot + <LANG>.po files, which contain the actual
translations. I thought I needed to generate those labels (eg.
"area_details") from my Python code, but you say that this is a
misconception.



Kind regards,
