Thanks Michael. Unfortunately, I can't cheat so I'm limited to (b).

       <summary dataCount="2"/>

The number of elements within <data> is variable. I need to calculate the dataCount attribute from the number of <data> elements. What is a good solution for this? I'd rather not use a second transform step unless absolutely necessary.



Three solutions:

(a) go back to the input document and calculate the information from
that
(b) a two-stage transformation
(c) cheat, by using saxon:assign or similar.

I would go for (b).
