Plain Old XML (POX) is the basic XML sometimes mixed in with other blendable specifications like XML Namespaces Dublin Core XInclude and XLink. This contrasts with complicated multilayered XML specifications like those for web services or RDF. The term may have been derived from or inspired by the expression plain old telephone service (a.k.a. POTS) and similarly Plain Old Java Object (POJO).An interesting question is how POX relates to XML Schema.
