In your code I see the following two lines:

xml_schema::document_simpl doc_s (*msgSSkel, 
                                  msgSAggr.root_name (),
                                  true,
                                  MSG_sskel::_static_type ());

doc_s.add_prefix("msg", "XTest.XBase.Domain.Msg");

The first line tells XSD/e that the root element is unqualified, which
is not correct in your case. So we need to change it to pass the root
element namespace in addition to its name:

xml_schema::document_simpl doc_s (*msgSSkel, 
                                  msgSAggr.root_namespace (),
                                  msgSAggr.root_name (),
                                  true,
                                  MSG_sskel::_static_type ());

The second line maps the 'XTest.XBase.Domain.Msg' namespace to the 'msg'
prefix while we want it to be mapped to "no prefix" (default namespace).
So we need to change this lime like so:

doc_s.add_prefix("", "XTest.XBase.Domain.Msg");
