This DTD supports both the E-utilities and ftp service data dissemination methods.
It is based on http://dtd.nlm.nih.gov/ncbi/pubmed/out/pubmed_180101.dtd
Additions/Changes since 180101 DTD:
1. Added MathML3
2. Allowed <mml:math> in <AbstractText>, <ArticleTitle>, <BookTitle>, <CollectionTitle>,
<Keyword>, <VernacularTitle>.
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).
NOTE: StartPage and EndPage in Pagination element 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
