Duh.  Of course I can.

There is a small drawback in performance from evaluating the list
every time it's called (which is pretty often), but given the
heinousness already perpetrated by my stylesheets, that won't be a big
deal.  (My sysadmins love me.  Can you say "98% CPU usage, boys and
girls?")

So that's the practical answer.  The more interesting, but not
immediately useful, theoretical question is: What if I couldn't?  What
if I needed to access some property of the root node of the document
outside of an node context?  What would I do?
