From 0cf6f3e86ec663c19baf64fd72556da185ba10d6 Mon Sep 17 00:00:00 2001
From: Michael Smith <xmldoc@users.sourceforge.net>
Date: Sat, 14 Jul 2007 19:58:59 +0000
Subject: [PATCH] Changed handling of reference auto-labeling such that
 reference (when it appears at the component level) is now affected by the
 label.from.part param, just as preface, chapter, and appendix.
