If you pass in a list of 2-item tuples (like [(1,1), (2,1), (3,1)]),
then sequence-key is the first item of every 2-item tuple, and
sequence-item is every second element. This also works for any other
combo of tuples and lists, as long as the contained lists/tuples are two
items long.

 <dtml-in "[(1,1), (2,1), (3,1)]">
   &dtml-sequence-key;: &dtml-sequence-item;<BR>
 </dtml-in>

would print

 1: 1
 2: 1
 3: 1

The objectItems method, for example, returns a list of id, subobject
tuples. sequence-key would then hold the id, and sequence-item the
subobject.
