Number of <disp-formula> elements that appear in an article
By convention, both numbered and unnumbered display equations are counted.
Many elements in this DTD 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 DTD to the Archiving DTD. 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 DTDs that were examined in the course of preparing this DTD used this mechanism, an inheritance of the older MAJOUR-header DTD.
