我正在尝试创建一个在 Orbeon 服务器中运行的具有嵌套重复的表单。这个想法是让一些元素可以重复，而第一个元素中的其他元素也可以重复。即用于插入个人信息的块（重复的几个人），对于每个人，我们可以添加几个电话号码（也是重复的）。
我还没有找到太多关于如何做到这一点的信息，我想我可以创建这个：其他 StackOverflow 问题（但这个例子对我也不起作用，即使评论中公开了更正）。
为了测试，我创建了下一个表单：

但只显示“嵌套重复”而不是“外部”重复。
问题是：它不是在 Orbeon 中实现的吗？它需要特定的语法吗？或者有什么我看不到的错误？
我正在使用 Orbeon 4.3.0.1.201308150213-CE。
编辑： 我已经更改了循环的“模板”部分并进行了一些更正。
