xsd：限制属性大于其他属性（相对验证）

Question

我正在根据伴侣属性valid-till搜索限制属性valid-from输入的方法。

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
   <xs:complexType name="Data">
      <xs:sequence>
        <xs:element name="material" type="Material" maxOccurs="unbounded" />
      </xs:sequence>
      <xs:attribute name="id" type="xs:ID" />
      <xs:attribute name="valid-from" type="xs:dateTime" />
      <xs:attribute name="valid-till" type="xs:dateTime" />
   </xs:complexType>
</xs:schema>

我如何实现这一目标？

最好的开始方式可能是进行网络搜索，或搜索Stack Overflow。查看

中的任何一个或全部

• Is there any way in xml schema to let an attribute always be greater than another one in an xml element?
• Validating the child's age against the parents age in xsd
• XSD assertions conditioned by the existence of attributes
• Restrict attribute value depending on value of another attribute
• XSD: Define attributes based on the value of previous attribute
• XML schema attribute dependancies

或搜索“xsd断言”，“xsd断言”，“xsd同现约束”。
