Lead story: PunchOut and static cXML catalogs solve different buying problems
The cXML standard covers both catalog content and PunchOut. A buyer-hosted catalog favors governed local content and predictable search when items are stable enough to synchronize. PunchOut favors supplier-hosted configuration and current context when a live session is available. Selection should preserve content volatility, configuration needs, buyer context, session dependency, payload ownership, availability, and order handoff.
