The "pyxb" binding generation generates a Python class for each type defined in the schema. You just instantiate such a class, populate the resulting object (in the normal Python way) and either use it in the construction of larger objects or serialize it as XML -- no need to worry about special construction ("objectivity.DataElement", "objectivity.SubElement", ...), no need to worry about xml namespaces.
