Deletion of Procurement PunchOut (2nd nomination)

Comment: selectively to cXML, where it is mentioned. As seen from the "further reading" book sources in the article, PunchOut is a particular e-procurement process based on the cXML protocol from SAP Ariba.  This article seems to try to make it a more general concept, but I haven't found sources that claim this is true--perhaps a non-neutral POV?  There are independent RS, such as the books, verifying basic facts about PunchOut. But I have not found the multiple in-depth RS needed to achieve notability. Hence a selective merge to cXML is probably the best |alternative to deletion for the sourcable material. In terms of what to merge, I would recommend just a few sentences from the lead and the references
Stance: merge
