This is (probably) because as an expression 'sequence-item' is
interpreted as 'sequence' - 'item' (subtraction). You can
<dtml-let si=sequence-item> and than use si in expressions without any
problem. Or, you can use _['sequence-item'] like you mention, which
indexes the namespace directly.

(Wonder why its not sequence_item, which wouldn't have caused any such
problem?)
