我有两个似乎无法解决的错误，也找不到适合我特定情况的解决方案...
所以我有错误：
s4s-elt-invalid-content.1：“ enginecapacityType”的内容无效。元素“限制”无效，放错位置或发生的次数过多。
s4s-elt-invalid-content.1：“ enginepowerType”的内容无效。元素“限制”无效，放错位置或发生的次数过多。
我的代码在下面。
能否请您帮我解决问题并解释为什么会发生？谢谢。

答案 0 :(得分：0)
您需要将这些元素声明为具有“具有简单内容的复杂类型”。参见此处的示例：XML Schema Restriction With Attribute
也许是这样的：
<xs:simpleType name="capacityType">
<xs:restriction base="xs:decimal">
<xs:minInclusive value="0"/>
<xs:maxInclusive value="5.0"/>
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="fuelType">
<xs:restriction base="xsstring">
<xs:enumeration value="petrol"/>
<xs:enumeration value="diesel"/>
</xs:restriction>
</xs:simpleType>
<xs:complexType name="engineCapacityType>
<xs:simpleContent>
<xs:extension base="capacityType">
<xs:attribute name="type" type="fuelType" use="required"/>
</xs:extension>
</xs:simpleContent
</xs:complexType>
