<!--                    NLM CITATION MODEL                         -->
<!--                    This structured citation model is provided
                        to assist users how are creating new content.
                        It 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. However,
                        this model does not provide guidance on what
                        information is required for each type of
                        cited content.

                        This 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.

                        In converting documents tagged to this
                        publishing DTD to the archiving/interchange
                        DTD the <nlm-citation> tag must be changed to
                        <citation> and all of the punctuation between
                        elements inside the citation must be inserted.
                                                                   -->
