recursion. call a named template with a parameter of 1; in the
template, do your copy (annotated with the parameter), add 1 to the
parameter, and use it as the parameter for another call of the same
template. back out when the parameter is > 4.

then again, the XT/Saxon node-set extension could also be used - make
your copies into an RTF, convert it to a node set, and iterate over it 
and look at generate-id() --- I bet you get unique values.
