<!--   NLMCatalogRecordSet DTD

       Comments and suggestions are welcome.
       January 1, 2013 

     **THIS IS THE CURRENT DTD FOR 2013 CURRENTLY IN USE. **
                            
       This is the DTD which NLM has written for Internal and External Use. 
       If you are a data Licensee, use the information
       from the NLMCatlogRecordSet. 
       
     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)).       
     
    
* = 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
