Do you mean using a node-set() extension function? Yes, you're right -
that would be another way. Create a result tree fragment containing
the correct answers, convert that to a node set using a node-set()
extension function and then count the number of nodes using the
count() function. This is probably less straightforward than counting
the correct answers directly (if that's possible), but more
straightforward than writing a recursive template.

(I hope you weren't suggesting using something like saxon:assign or
writing an extension function that updated a variable... ;)

Cheers,

Jeni
