推荐答案

如 XML 规范中所述:

定义:只有一个元素，称为根元素或文档元素，它的任何部分都不会出现在任何其他元素的内容中.[...] 由开始和结束标签分隔的元素相互嵌套.

Definition: There is exactly one element, called the root, or document element, no part of which appears in the content of any other element. [...] The elements, delimited by start- and end-tags, nest properly within each other.
