     =============================================================
     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. 
     
  2. Updated public identifier to "v2.3 20070202//EN"          

     =============================================================
     Version 2.0                       (DAL/BTU) v2.0 (2004-07-30)
         
     
     Major requirement changes led to the new release, producing
     DTD version "2.0":
       a) Suite remodularization to meet new (and newly articulated)
          modularization requirements

  1. Created this module from material previously in the single
     journal publishing customization module (journalpubcustomize.ent)

<!--                    This structured citation model is provided
                        to assist users how are creating new content.
                        It loosely reflects the NLM's style, in that
                        it allows the tagging of all "legal" NLM 
                        citations and enforces the sequence in which
                        content must appear if it is present. However,
                        this model does not provide guidance on what
                        information is required for each type of 
                        cited content. 
                        
                        This model assumes that punctuation between
                        the parts of a citation will be generated 
                        on display or on export from the XML tagged
                        according to this DTD to XML for another use.

                        DTD the <nlm-citation> tag must be changed to
                        <citation> and all of the punctuation between
                        elements inside the citation must be inserted.
