     Details concerning ANSI/NISO Z39.96-2012 JATS-based DTDs,  
     XSDs, RNGs and supporting documentation are available at
           http://jats.nlm.nih.gov/1.3d2/

  5. GLOBAL ATTRIBUTES - Added the new parameter entity 
         %jats-common-atts;
     to every element in this module. This PE adds (for now) the
     @id attribute and the @xml:base attribute to every element,
     whether metadata or narrative.
     Since the @id in this parameter entity is optional, a second
     parameter entity jats-common-atts-id-required was also added.
     The two are kept in sync with the jats-base-atts parameter 
     entity.
     This added an attribute list to:
      - floats-group
      - sec-meta
   
     =============================================================
     NISO JATS Version 1.0             (DAL/BTU) v1.0 (2012-xx-xx)

     XSDs, RNGs and supporting documentation are available at
           http://jats.nlm.nih.gov/1.3d2/
   
  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)

     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.

                        hold the floating objects that occur within
                        an article. Some publishers like to
                        collect all these floating objects (figures,
                        tables, text boxes, graphics, etc.) together
                        at the end  rather than interspersing them
                        throughout the various parts of the document
                        where they are referenced.
