Xml XSD限制partent元素的子元素数量

因此，我试图为我们将在程序中使用的XML文件定义一个模式。有一个元素具有子元素，该子元素定义整个文件的源语言和任何目标语言。始终只有一种源语言，并且每个translationUnit中的源语言必须相同。可以有任意数量的targetLanguages，但每个translationUnit必须具有完全相同的targetLanguages，它们不能不同

是否有一种XSD或其他模式格式的方法可以：

a） 是否要求每个translationUnits的sourceSegment的langLocale与jobLanguages元素中的sourceLang相同

b） 是否要求每个translationUnits的targetSegment元素的langLocale属性与jobLanguages元素的targetLang元素的langLocales匹配

本质上，随XML发送的每个请求必须在整个文档中保持一致，某些TranslationUnit不能有不同的源语言或一组不同的目标语言

示例XML文件：

这是一种类型设置，用于确保sourcString的长度大于0。本质上，使用空白sourceSegment是不正确的。

这是翻译文本的主体。没有允许的属性或限制。必须至少有一个translationUnit元素。
此元素封装项目的语言。此处列出的所有语言应与每个translationUnit中指示的语言匹配。
此元素封装了项目的源语言，并且应该与每个translationUnit的源语言匹配。这些元素中只能有一个，而且必须只有一个
此元素封装了项目的目标语言。每个translationUnit都应该有这些目标语言，没有例外。必须至少指定1种targetLanguage，但不能限制可以有多少种targetLanguage。每个目标语言必须是唯一的，并且targetLanguage不应等于sourceL语言。
这是翻译的主要单位，包括语言组合。应该只有一个sourceSegment元素，并且至少有一个targetSegment元素。每个targetSegment元素上的langLocale属性必须是唯一的。换句话说，每种语言只能有一个targetSegment。此外，任何targetSegment都不能与sourceSegment具有相同的langLocale。如果尚未存在翻译，则targetSegments应uld为空，但必须包含在文件中
用于翻译的文本放置在此元素中。每个translationUnit元素必须为1。不能为null，长度也不能小于1个字符。
这是源的语言区域设置组合。所有sourceString必须具有相同的语言区域设置
基于我们的API，语言区域设置组合的可用选项仅限于某些值。有关更多详细信息，请参阅Glyph最佳实践API文档。
