Number of <disp-formula> elements that appear in the document.
Best Practice: Although a NISO STS standards-producing organization could choose to record all the counts of objects in a standard using the <count> element, Best Practice is to use the specific count elements (<fig-count>, <equation-count>, <word-count>, etc.) whenever possible, using the <count> element only for ad hoc counts, organization-specific counts, standard-specific counts, and similar.
