How to make sure an element does not exist in XSD?

Question

Can I use maxOccurs="0"?

Example:

<xs:element name="person">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="full_name" type="xs:string"/>
      <xs:element name="child_name" type="xs:string" maxOccurs="0"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

Do you have a better way for this?

Answer 1

好吧，只要minOccurs="0"，您就可以设置maxOccurs="0"，但更常见的是，您只需省略该元素以防止它出现：

<xs:element name="person">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="full_name" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>
