     Version 3.0 is the first non-backward-compatible release.
     In addition to the usual incremental changes, some
     elements and attributes have been renamed and/or remodeled
     to better meet user needs and to increase tag set consistency.
     All module change histories are available through the Tag Suite 
     web site at http://dtd.nlm.nih.gov.

<!--                    This structured citation model is loosely 
                        reflects the NLM's house 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.
                        This model assumes that punctuation between
                        the parts of a citation will be generated 
                        on display or on export.
