From bc3ce0aac8385dc44e988ce953e93ba6b0ae1450 Mon Sep 17 00:00:00 2001
From: Marc Cromme <marc@indexdata.dk>
Date: Wed, 18 Apr 2007 07:41:03 +0000
Subject: [PATCH] encapsulating all record fields in a xsl:for-each to prevent
 emitting empty <md-title> elements. Now all emitted
 elements have always content, and the final web client JS
 does not break any more.
