【问题描述】：
我正在为我的 orbeon 表单添加一些多语言支持。对于这个范围，我添加了几个不同语言的资源<resource xml:lang="en">[...]</resource><resource xml:lang="it">[...]</resource>
我发现，如果我有两种语言，单选按钮选项会重复出现（每个答案我可以看到两次）。一个简单的例子是：
<xh:html xmlns:xh="http://www.w3.org/1999/xhtml"

结果在哪里：
一项小型研究和测试，似乎该问题与部分定义中的“嵌套”问题有关。
<Category>
<label>Category</label>
<hint/>

<label>Question</label>

如果我把它改成：
<Category>
<label>Category</label>
<hint/>
<alert/>
</Category>
<Question>
<label>Question</label>
<hint/>
<alert/>
<item>
<label>Answer</label>
<hint/>
<value>Answer</value>
</item>
<item>
<label>Answer2</label>
<hint/>
<value>Answer2</value>
</item>
<item>
<label>Answer3</label>
<hint/>
<value>Answer3</value>
</item>
</Question>
似乎工作正常。我知道 Orbeon 构建器不会在资源部分中嵌套元素，但总的来说我更喜欢这样做，我认为这样更便于阅读（或使用元素的 XPath）。
有没有办法使用嵌套元素来解决这个问题？
