 **New in development version:** If you're using :ref:`named URL patterns
 <naming-url-patterns>`, you can refer to the name of the pattern in the ``url``
 tag instead of using the path to the view.
+If you need to save the url to a context variable instead of inserting the url 
+where the tag is use the syntax::
+
+    {% url path.to.some_view arg1,arg2,name1=value1 %}
+
+This is useful for translated text which cannot contain tags, so you need to use
+variables instead.
