Here's one way to do it. There may be others:

<dtml-in blah mapping>
<dtml-var _['sequence-item']['val']>
</dtml-in>

The 'mapping' parameter to dtml-in causes it to treat the sequence items as
mappings instead of instances. Then "_['sequence-item']" refers to the
dictionary object and "_['sequence-item']['val']" refers to the 'val' element of
that dictionary.
