The size (such as running time, page count, or physical dimensions) of an object, such as a product (software package, video, audio book, hardware component, etc.) that is being reviewed
The units attribute must be used to name the unit of measure (minutes, hours, linear feet, pages, etc.).
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>.
