Another common practice is to introduce an element in the 'tal'
namespace to group the repeated elements;  such tags are automatically
omitted when rendered.  E.g.:

  <dl>
   <tal:loop tal:repeat="finfo folder_info">
    <dt><a tal:attributes="href finfo/url"
           tal:content="finfo/alias">THE_TERM</a></dt>
    <dd tal:content="finfo/summary"THE_DEFINITION</dd>
   </tal:loop>
  </dl>

This technique has the advantage of not confusing tools which think they
know what the correct content model for '<span>' is (of course, they
need to be willing to ignore elements from unknown namespaces).
