Also, depending on the original problem, sometimes you don't even need the 
original aggregation step, or can perform it in such a way that you can 
aggregate a node set, not an RTF. (One would have to see that for-each loop 
to know in your case. Does its operation merely collect a node set, or does 
it do something more complex?) If you can do this, you can process this 
node set; the problem goes away.

What follows is a variable containing a for-each loop that collects the
nodes needed for further processing later in the XSL. As far as I can tell,
it is simply collecting the nodes based on certain criteria. If this can be
translated into a node-set, I would certainly appreciate pointers on how to
modify it.  
Thank you,
