     =============================================================

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

     =============================================================
     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
  
  2. Updated public identifier to "v2.0 20040830"          

     =============================================================
     Version 1.1                           (TRG) v1.1 (2003-11-01)

  1. Added attribute "alternate-form-of" to <mml:math> 
     (Note: parameter entity %math.qname; resolves to <mml:math>.)
     Rationale: Where multiple formats of an item (e.g., graphic 
     file, media object, chemical structure) are available, this 
     attribute indicates that a format is a secondary one and 
     provides a link to the primary format, so that only one 
     format of an item is displayed.
                                                                   -->
