xsd：限制一个属性大于另一个（相对验证）[重复]

Question

我正在寻找一种方法来根据伴随属性valid-from 限制属性valid-till 的输入。

<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>

我怎样才能实现这个目标？

Answer 1

可能最好的开始方式是进行网络搜索，或在 Stack Overflow 上进行搜索。查看任何或全部

• 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

或者搜索'xsd assertion'、'xsd assert'、'xsd co-occurrence constraint'。
