I've noticed two different xmls namespaces for the core cordova plugins : xmlns="http://www.phonegap.com/ns/plugins/1.0" and xmlns="http://cordova.apache.org/ns/plugins/1.0"
I believe we want the second namespace but the documented plugin spec [1] uses the first one (probably hasn't been updated). Is it safe to say that we want http://cordova.apache.org/ns/plugins/1.0 as the namespace for the core cordova plugins? [1]: https://github.com/alunny/cordova-plugin-spec
