Hi Marco,
we have to write in English, we abused too much yet of italian language.
It's don't need necessary to fulfill the components CONTROLLER, you have map in ABAP only the fields you wants to view in XML files.
You have also to consider that not all fields of official scheme are mandatory.
When you call the method cl_proxy_xml_transform=>abap_to_xml_xstring the XML will contains only tags filled.
