//
// Known limitations
// - output still in html, because the errors are not displayed in xml
// - could not set the external keys by the mean of a reconciliation (the exact key must be given)
// - reconciliation is made on the first column
// - no option to force 'always create' or 'never create'
//
// Known issues
// - ALMOST impossible to troubleshoot when an externl key has a wrong value
// - no character escaping in the xml output (yes !?!?!)
// - not outputing xml when a wrong input is given (class, attribute names)
// - for a bizIncidentTicket you may use the name as the reconciliation key,
//   but that attribute is in fact recomputed by the application! An error should be raised somewhere
