These days, instead of the fairly horrible hard to explain _['sequence-item']
you can use 'prefix' instead, like this. The problem is that - in Python
means substraction and therefore cannot be part of a name, and due to
historical reasons Zope does use the - in DTML as part of names. The
prefix knob fixes this as it makes dtml-in use an underscore instead:

<dtml-in something prefix="seq">
  <dtml-var seq_item>
</dtml-in>

See also the online DTML help on 'in'.
