我很难理解ansible with_subelements语法的逻辑,with_subelements究竟做了什么？我在http://docs.ansible.com/ansible/playbooks_loops.html#looping-over-subelements上查看了有关with_subelements的ansible文档,并没有太大帮助.我还在博客上看到了带有with_subelements示例的剧本

     shell: useradd -c "{{ item.1 }}" "{{ item.0.name }}"
     with_subelements:

item.1和item.0引用了什么？
