Equation Count


Number of <disp-formula> elements that appear in an article


By convention, both numbered and unnumbered display equations are counted.

Unlike <disp-formula>s, inline equations (<inline-formula>) are not counted.

Many elements in this Suite were created explicitly for import conversion, that is, so that the intellectual work of tagging done by publishers would not be discarded when they converted material from another tag set to the Journal Publishing Tag Set. The count elements are a perfect example of this rationale; they are conversion elements, not for authoring, and should only be tagged if present in the original source.

The count elements are modeled as EMPTY elements (that is, elements that have no content and store their real values in one or more attributes) because the majority of journal tag sets that were examined in the course of preparing this one used this mechanism, an inheritance of the older MAJOUR-header DTD.

Related Elements

Inside the <counts> wrapper element are the counts of various components of the article: the <fig-count> is the number of figures, the <table-count> is the number of tables, the <equation-count> is the number of equations, the <ref-count> is either the number of references or (more properly) the number of citations in the bibliographic reference list, the <page-count> is the page count, and the <word-count> is the number of words in the article.
