<!-- NLM Serials DTD
Comments and suggestions are welcome.
January 1, 2008
SEE http://www.nlm.nih.gov/databases/dtd/nlmserials_090101.dtd FOR THE
FORTHCOMING NLMSERIALS DTD DATED JANUARY 1, 2009 FOR FUTURE USE.
This is the DTD which the U.S. National Library of Medicine
has written for External 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., NLMMedline DTD, 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
-->
<!-- ================================================================= -->
