Need help with xtk:builder#UpdateDb XML parameter structure (Beginner)

Actually I used BuildUpdateOneSchemaDiff. I am using a payload generator by parsing the wsdl into the payload. the request method looks like this:
 

def build_update_one_schema_diff(self, namespace , name , useNamingConventions):
        gen_req = soapRequests(
                method="BuildUpdateOneSchemaDiff",
                wsdl_json_path="schemaJsonCollection/xtk_builder.json", 
                parameters={
                    "sessiontoken": os.getenv("ADOBE_SESSION_TOKEN"),
                    "strSchemaId": f"{namespace}:{name}",
                    "useNamingConventions": useNamingConventions
                }
            )
        gen_res = gen_req.send_request(url=os.getenv("ADOBE_INSTANCE_URL"))
        return gen_req , gen_res

it essentially generates this payload
