OK, mylist is now a list of strings.

><dtml-in mylist>

></dtml-in>

That shouldn't work -- sequence-item is a string, while dtml-with expects an
object.  Try this instead::

 <dtml-in mylist>
  <dtml-let refID=sequence-item> <!-- alias sequence-item -->
   <dtml-with "_[ refID ]">      <!-- "dereference" refID -->
    <dtml-var id>                <!-- use the object      -->
   </dtml-with>
  </dtml-let>
 </dtml-in>
