I would personally do this in a Python script. But, here is a way in
DTML. Basically, you can access properties without worrying about
acquisition by using the hasProperty and getProperty methods of the
Folder. Something like:

<dtml-in expr="objectValues('Folder')" skip_unauthorized>
    <dtml-if expr="getProperty('in_the_list', 0)">
        do stuff
    </dtml-if>
</dtml-in>

You don't need the _['sequence-item'] stuff because dtml-in already puts
the current object at the top of the namespace stack for you.
