<!--
     =============================================================

Version  Reason/Occasion                   (who) vx.x (yyyy-mm-dd)

     =============================================================
     Version 2.3                       (DAL/BTU) v2.3 (2007-02-02)
     
     Enhancement Release (2.3) following the Working Group meetings 
     of Oct-Nov/2006-Jan/2007. No backward-incompatible changes.
     Archiving loosened even more. New structures for all the DTDs. 
     
  3. Updated public identifier to "v2.3 20070202//EN"          

     =============================================================
     Version 2.0                       (DAL/BTU) v2.0 (2004-08-30)
     
     Major requirement changes led to the new release, producing
     DTD version "2.0":
       a) The splitting of the Archival and Interchange Tag Set 
          DTDs into three DTDs from two: an authoring DTD, an
          archive regularization and interchange DTD (the
          current Blue Publishing DTD), and a preservationist 
          archive DTD (the current Green Archiving and Interchange 
          DTD).
       b) AIT Working Group suggestions from the June 04 meeting 
          and June/July 2004 followup discussions
       c) Suite remodularization to meet new (and newly articulated)
          modularization requirements
       d) New or renamed classes and mixes to make modifications
          easier and more consistent
          modularization requirements.

  2. LATEX - Added as a notation for display and inline formulas  
  
  1. Updated public identifier to "v2.3 20070202"                  -->
