Structured citation model to assist users creating “new” content; the model 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.
Note: This model does not provide guidance on what information is required for each type of cited content. Moreover, the 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. For extensive examples of formatted <nlm-citation>s see: Sample PubMed Central Citations. To see tagged versions of these examples, see: Sample PubMed Central Citations - XML Tagged.
