From a93ddf92d90ee5ef8a4995488dc330b289bcdde8 Mon Sep 17 00:00:00 2001
From: Glen Mazza <gmazza@apache.org>
Date: Sat, 20 Dec 2003 17:40:01 +0000
Subject: [PATCH] Property Makers now being activated via int constants. 
 (Maker classes themselves, as well as code referencing the properties, still
 need conversion to int's.  Also, HashMaps for String and Integer in
 FOPropertyMapping and FObj temporarily being retained for troubleshooting
 purposes.)  Contribution mainly from Finn Bock (Bug #25480).
