Size of a resource or object described in a bibliographic reference or product. The @units attribute must be used to name the units of measure (for example, minutes, hours, linear feet, pages).
Related Essay: For a discussion on the use of <size>, see Length and Size.
Best Practice: In the metadata for an article, the element <page-count> records the number of pages in a print article, and the <page-range> records additional page information such as discontinuous ranges. In the description of a <product>, number of pages should be recorded using the <size> element, which can also be used for running time and other measurements of size/length. Thus, best practice does not use <page-count> inside <product>.
