Reference Count

Records the total number of either a) the references (<ref>) or (more properly) b) the number of citations (<mixed-citation>) that appear in the bibliographic reference list (<ref-list>) for a book. This count is (roughly) the number of sources cited in the book.


The count elements are modeled as EMPTY elements that have no content but carry values on their attributes.
