Generic count element to count anything a BITS user organization may wish to count in a document. The @count-type attribute will name what is being counted (such as footnotes, tables, sections, contributors, images, etc.) The @count attribute will state how many of the objects are in the document.
Best Practice: Although a BITS user organization could choose to record all the counts of objects in a document using this element, the specific count elements (<fig-count>, <equation-count>, <word-count>, etc.) should be used whenever possible, using the <count> element only for ad hoc counts.
