This is interesting in that you want to key on a document that is passed
in as a parameter.  This should work fine, but I've certainly never done
it.  Instead, I pass the XML into the stylesheet as a string and then
use the extension saxon:parse() on it to create a nodeset.  This is
simpler than doing the work in the host language.

This is useful when the XML that is passed in as a paramter is created
dynamically, if the document already exists at the end of a url you
should use the document() function - isn't that sufficient for what you
need here?
