---++ 20121123 TODO jgu post SimpleRegistryService
* SimpleRegistryService : link SRS in wiki, cleanup RegistryApi tries, there add archi comment ("powerful but complex biz (requires knowing Nuxeo model) & tech (custom MessageBodyReader/Writer for returning lists without roots and magically handling all property types including list), requires jersey client, else use SRS"),
* v1SOAPDiscovery handler : add / rewrite junit test (inspired by event ex. starter & nuxeoMock, using WS mock ex. meteo), also update event test
* AXXX Pivotal : see TODOs in README.md
