yes, such a syntax should _theoretically_ do the proper thing, but I always get a
"Error Value: sequence index must be integer" when trying to do the [start:end] stuff within the <dtml-in> Tag.
 
Any Ideas how I could either
a) use "DATA[start: x + y]" in Zope (where x and y are dtml-Variables!)
b) do <dtml-in DATA start=1 end= x + y (where x and y are dtml-Variables!)
 
Thanks again,
Philipp
