You are sooo close.

You cannot use _['sequence-item'].id because _[] calls the object if it
is callable, which results in a string for DTML objects.

If you are in a dtml-in loop, there is no need to dereference
sequence-item explicitly, dtml-in already puts all of its attributes on
the namespace inside the loop.

<dtml-in "Folder.objectValues()">
  <P>Object ID = <dtml-var name="id"></P>
</dtml-in>

will suffice, however it is overkill, the following is more efficient:

<dtml-in "Folder.objectIds()">
  <P>Object ID = <dtml-var name="sequence-item"></P>
</dtml-in>
