Hi Jon,
What you want it profiling, which does exactly what you want and much
more. It's explained in Bob Stayton's excellent book:

http://www.sagehill.net/docbookxsl/Profiling.html

Btw., what you were doing would work if you did apply-imports instead.
When you do apply-templates you override the templates that normally
handle rows and so produce invalid xsl-fo. But what you really want is
profiling.
