我从验证器收到此错误:
S4s-elt-invalid-content.1:'schema'的内容无效。元素'键'无效,错位或太频繁发生。
如果我删除键/ keyref它可以正常工作但如果我包含它则不行。我无法弄清楚错误是什么,谷歌搜索和搜索在这里没有显示任何可以解决此密钥/参考问题。任何帮助将非常感激。

您的XSD部分似乎缺失,可能是由于努力创建最小的完整示例。但是,您的错误的直接原因是xs:key
和xs:keyref
元素不能是xs:schema
元素的子元素。
把它们放在xs:element
元素的孩子们的最后(在任何xs:simpleType
或xs:complexType
之后,在</xs:element>
之前)。然后将XPath调整到新的上下文。
