    I solved exactly this same problem for a client recently 
    (in a real application involving financial reporting up an 
    organization hierarchy).
    It's a tricky one, but the final solution is remarkably 
    concise, at least in XSLT 2.0.
    
    To give you a sketch of the solution: there is a recursive 
    named template that takes as input a set of elements and a 
    level number: the template calls xsl:for-each-group to do 
    one level of grouping, calling a function to calculate the 
    grouping key for level N; within the for-each-group it then 
    makes a recursive call-template to group the elements in 
    current-group() at level N+1. The function that calculates 
    the grouping key for level N reads the Nth XPath expression 
    from a configuration file, and calls
    saxon:evaluate() to evaluate it.

I need a Jeni to translate that...
 Are either of our Jeni's around today :-)
