 * This is a standard Product page-type with fields like

 * It also has an associated Product_OrderItem class,
 * an extension of OrderItem, which is the mechanism
 * that links this page type class to the rest of the
 * eCommerce platform. This means you can add an instance
 * of this page type to the shopping cart.
