It selects the CD element within the root CDS element, which has a title attribute equal to August and Everything After, all in the cd.xml document.
它选择了根元素cds中的cd元素，该元素有一个title属性等于AugustandEverythingAfter，这些内容都在cd . xml文档中。
So where, in XPath, you'd apply a path like /cds/cd[title='Revolver'] to a specific document, you can indicate the document in your actual XQuery using the doc() function.
前面我们已经将路径 /cds/cd[title='Revolver'] 应用到了一个特定的文档，但在XQuery 中可使用doc() 函数指定文档。
This returns all attributes named "title" that are on CD elements, nested within a root element named CDS.
