Thank you Romain. With a bit of tweaking that does exactly what I want.

Right now, the only thing I can see to do is to use another bit of XSLT to generate an XProc pipeline and execute that. I would prefer to be able to do this without that and simply express this as some sort of iteration in XProc.
