Since the root= is not specified in the self.get_optional_child call and "batch_query" is not a child of self in most cases but it's grandchild, it will return None. Since we have at list two children (one in config_batch.xml in ccs_config/machines and another one in the machine directory). The trival fix would be too loop through "batch_system" and take the last "batch_query" that is not None. Should I fire a PR?
