   Tellico XSLT file - used for exporting to HTML

   Copyright (C) 2004-2006 Robby Stephenson - robby@periapsis.org

   This XSLT stylesheet is designed to be used with the 'Tellico'
   application, which can be found at http://www.periapsis.org/tellico/

   The exslt extensions from http://www.exslt.org are required.
   Specifically, the string and dynamic modules are used. For
   libxslt, that means the minimum version is 1.0.19.

   This is a horribly messy stylesheet. I would REALLY welcome any
   recommendations in improving its efficiency.

   The app itself adds group elements that aren't in the data file
   itself, in order to speed up exporting. So if this stylesheet is
   being used outside the app, it should still work, but may give
   slightly different results than when exporting to HTML from
   within Tellico.

   Customize this file in order to print different columns of
   fields for each entry. Any version of this file in the user's
   KDE home directory, such as $KDEHOME/share/apps/tellico/, will
   override the system file.
