This could probably be formalised into three categories: data that _must_ be stored in an attribute, data that _cannot_ be stored in an attribute, and everything else. For example: MUST: * Enumerated values (status can be active, inactive or closed). CANNOT: * Structured information * White space matters * order is significant * More than one item for any one name OTHER: * General string values * URL's Maybe the wisdom of experience could subdivide OTHER into SHOULD, SHOULDN'T and DOESN'T MATTER (which could address the namespace pollution issue).
