     =============================================================
     NISO JATS Version 1.0             (DAL/BTU) v1.0 (2012-xx-xx)
   
     ANSI/NISO Z39.96-2012 (Version 1.0) 

     Details concerning ANSI/NISO Z39.96-2012 JATS-based DTDs, XSDs, 
     RNGs and supporting documentation are available at
           http://jats.nlm.nih.gov/1.0/
   
  4. Updated the DTD-version attribute to "1.0" and the formal
     public identifier to the date: "v1.0 20120330//EN".

     =============================================================
     Version 0.4                       (DAL/BTU) v0.4 (2011-01-31)
   
     This Tag Set is in the process of becoming a NISO standard.
     The version numbers are starting over from 0.4", as a Trial
     Use Draft, to be made into "Version 1.0" when the Tag Suite 
     becomes a NISO standard. Thus, the version number that would
     have been "NLM Version 3.1 Draft" has become NISO JATS
     "Version 0.4".

     Details on NISO Trial Use Draft Version 0.4 are available at
           http://jats.nlm.nih.gov/JATS-0.4.
   
  3. Updated the DTD-version attribute to "0.4" 
   
  2. Updated the public identifier to "v0.4 20110131", 
     modified the formal public identifier to include "JATS (Z39.96)",
     and the filename as delivered to include "JATS" and the
     new version number "0".

     =============================================================
     Version 3.0                       (DAL/BTU) v3.0 (2007-10-31)

     Version 3.0 is the first non-backward-compatible release.
     In addition to the usual incremental changes, some
     elements and attributes have been renamed and/or remodeled
     to better meet user needs and to increase tag set consistency.
     All module change histories are available through the Tag Suite
     web site at http://dtd.nlm.nih.gov.

     Details on version 3.0 are available at
           http://dtd.nlm.nih.gov/3.0.

  1. Updated public identifier to "v3.0 20080202//EN"              -->
