+String literals passed to tags and filters
+------------------------------------------
+
+You can translate string literals passed as arguments to tags and filters
+by using the familiar ``_()`` syntax::
+
+    {% some_tag _("Page not found") value|yesno:_("yes,no") %}
+
+In this case, both the tag and the filter will see the translated string,
+so they don't need to be aware of translations.
+
+.. note::
+    In this example, the translation infrastructure will be passed the string
+    ``"yes,no"``, not the individual strings ``"yes"`` and ``"no"``. The
+    translated string will need to contain the comma so that the filter
+    parsing code knows how to split up the arguments. For example, a German
+    translator might translate the string ``"yes,no"`` as ``"ja,nein"``
+    (keeping the comma intact).
