With difficulty. The following approaches can be used in XSLT 1.0 to sum a
set of computed values:

(a) create the computed values in a new tree, convert it to a node-set using
xx:node-set(), then sum over the new nodes.

(b) use a recursive scan of the input, accumulating the total as you iterate
over the values

(c) use the appropriate higher-order function as defined in the FXSL
library.
