     =============================================================
     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.
