【问题描述】：
所以我在我的照片元素的 xsd 文件中不断收到此错误，它显示“s4s-elt-must-match.1：'目录'的内容必须匹配（注释？，（simpleType | complexType）？，（ unique | key | keyref)*))。发现问题从：元素开始。”

This photo was taken by John Borelli's great-grandfather. It is believed to have been taken around 1830.
David Demarest originally purchased the site of the chair factory in 1663. This site was under the ownership of the Demarest family until 1758. The property is listed in the National and New Jersey Registers of Historic Places.

【问题讨论】：
-
请检查您输入的 XSD 和 XML 是否正确。反引号中的“在此处输入代码”文本看起来很不合适，并且有些元素未关闭。这显然不是一个有效的架构，但错误与您报告的错误消息没有明确的关系，所以我怀疑除了真实错误之外，我们还看到了虚假错误。
