It's just basic Python syntax for lists. In Python, if you have a variable
called list, you get the 2nd element in the list by
list[1]
(The indexing is zero-based).
In Zope, with a Zope variable again called list, you can get its 2nd
element using
<dtml-var "list[1]">
In other dtml expression, you refer to the element the same way.
