Roger,

This was discussed and implemented 6-7 years ago -- quite a general
approach to generating the closure of any function from node to nodes,
starting from a given initial set of nodes:

    http://dnovatchev.wordpress.com/2007/11/04/closure-in-xslt/

In my blog post from that time there are links to the code of f:closure():

  http://fxsl.cvs.sourceforge.net/fxsl/fxsl-xslt2/f/func-closure.xsl?revision=1.1&view=markup&sortby=date

and to a couple of tests.

There is also a link to Rick Jelliffe's original message in this same
mailing list that started all of this:
