Eureka!!! After wasting nearly a full day on this, I've finally figured it
out. The correct code is:
<dtml-in "PARENTS[0].objectValues(['DTML Document'])">
<dtml-var "_.getitem('sequence-item').id">
</dtml-in>
Apparently the first method evaluates 'sequence-item', which causes the
recursion since the document containing the code is itself in the sequence.
Ouch!
