-<!-- NLM MedlineCitationSet DTD
-
-     This is the DTD which NLM has written for Internal and External Use.
-     January 1, 2013
-     
-    **THIS IS THE CURRENT DTD FOR 2013 CURRENTLY IN USE. **
-         
-     NOTE:  The use of "Medline" in a DTD or element name does not mean the record 
-     represents a citation from a Medline-selected journal.  When the NLM DTDs and 
-     XML elements were first created, MEDLINE records were the only data exported. 
-     Now NLM exports citations other than MEDLINE records using these tools. To 
-     minimize unnecessary disruption to users of the data and tools, NLM has
-     retained the original DTD and element names (e.g., NLMMedlineCitationSet, 
-     MedlineTA, MedlineJournalInfo)).  
-
-     NOTE:  StartPage and EndPage in Pagination element and NameID in Author
-     and Investigator elements are not currently used; are reserved for future use.  
-                
-
-        * = 0 or more occurrences (optional element, repeatable)
-        ? = 0 or 1 occurrences (optional element, at most 1)
-        + = 1 or more occurrences (required element, repeatable)
-        | = choice, one or the other but not both
-        no symbol = required element

+
+	Additions/Changes since 160101 DTDs: This new DTD supports both the E-Utilities 
+	and ftp service data dissemination methods. It is based on 
+	https://www.ncbi.nlm.nih.gov/corehtml/query/DTD/pubmed_160101.dtd
+
+	1.  Added optional Conflict of Interest tagging to MedlineCitation as CoiStatement.
+	2.  Added @IndexingMethod to MedlineCitation.
+	3.  Added @EqualContrib to Author.
+	4.  Added @RefType for expression of concern enrichment to CommentsCorrections.
+	5.  Deleted the Partial Retraction enrichment from @RefType on CommentsCorrections.
+	6.  Deleted MedlineCitationSet.
+	7.  @Type on AuthorList and HTML formatting elements in some text areas (AbstractText,
+		Affiliation, ArticleTitle, CollectiveName, Keyword, Suffix, VernacularTitle) were
+		available in the pubmed_160101.dtd, but these may be perceived as additions to 
+		users of the nlmmedlindecitationset_160101.dtd.
+	8.  Users accustomed to the nlmcitationset DTDs will also notice "new" elements that 
+		support the dissemination of the book citations from PubMed while using E-Utilities.  
+		The ftp server dissemination method provides only journal citations.
+	9. @Type on AuthorList changed to #IMPLIED.
+	10. Added InvestigatorList to Book and BookDocument.
+
+	NOTE:  The use of "Medline" in a DTD or element name does not mean the record
+	represents a citation from a Medline-selected journal.  When the NLM DTDs and
+	XML elements were first created, MEDLINE records were the only data exported.
+	Now NLM exports citations other than MEDLINE records using these tools. To
+	minimize unnecessary disruption to users of the data and tools, NLM has
+	retained the original DTD and element names (e.g., MedlineTA, MedlineJournalInfo).
