&lt;div&gt;Why not use DL for name-value pairs? --[[User:Etoastw|Etoastw]] 05:52, 27 Feb 2007 (PST)&lt;br /&gt;

On UPC and product codes:&lt;br /&gt;
The properties 'isbn' and 'upc' are anticipated for p-v keys. They should be extended by other common properties (p.e. 'issn') and at least the EAN, which is now world-wide standard for product codes. isbn and upc are covered by the EAN and can be converted to and from the EAN.&lt;br /&gt;
