在哪里放置 XSD 1.1 断言?

Where to place an XSD 1.1 assert?

我尝试使用 xs:assert 根据两个属性的值进行验证,但未成功。我不断收到

s4s-elt-must-match.1: The content of data must match (annotation?, (simpleType | complexType)?, (unique | key | keyref)*)). A problem was found starting at: assert.

我查看了一堆问题。我什至复制了给出的答案之一,但即使它给出了同样的错误。它告诉我测试的格式无效,但我找不到任何不同的例子。谁能告诉我我做错了什么?

TIA

这是我复制的答案,内联错误作为注释:

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:vc="http://www.w3.org/2007/XMLSchema-versioning"
  vc:minVersion="1.1">

  <xs:element name="data">
    <xs:complexType>
      <xs:attribute name="min" type="xs:int"/>
      <xs:attribute name="max" type="xs:int"/>
    </xs:complexType>
    <xs:assert test="@min le @max"/>
    <!--s4s-elt-must-match.1: The content of 'data' must match (annotation?, (simpleType | complexType)?, (unique | key | keyref)*)). A problem was found starting at: assert.-->
  </xs:element>

</xs:schema>

编辑: 这是 complexType 中的断言,显示不同的错误。

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:vc="http://www.w3.org/2007/XMLSchema-versioning"
  vc:minVersion="1.1">

    <xs:element name="data">
        <xs:complexType>
            <xs:attribute name="min" type="xs:int"/>
            <xs:attribute name="max" type="xs:int"/>
            <xs:assert test="@min le @max"/>    
<!-- s4s-elt-invalid-content.1: The content of '#AnonType_data' is invalid.  Element 'assert' is invalid, misplaced, or 
 occurs too often. -->                      
        </xs:complexType>
    </xs:element>

</xs:schema>

可能的问题:

  1. 确保您的 XSD 处理器支持 XSD 1.1.
  2. xs:assert 元素移动到 xs:complex 内:

变化自

  <xs:element name="data">
    <xs:complexType>
      <xs:attribute name="min" type="xs:int"/>
      <xs:attribute name="max" type="xs:int"/>
    </xs:complexType>
    <xs:assert test="@min le @max"/>
  </xs:element>

  <xs:element name="data">
    <xs:complexType>
      <xs:attribute name="min" type="xs:int"/>
      <xs:attribute name="max" type="xs:int"/>
      <xs:assert test="@min le @max"/>
    </xs:complexType>
  </xs:element>
