Answer 1

在您的架构中，<xs:attribute.../>声明会进入<xs:complexType>...</xs:complexType>声明，并且必须在<xs:sequence>之后结束。

修复错误后，您在定义中的XSD中遇到另一个问题

<xs:element name="img">
    <xs:complexType>
        <xs:simpleContent>
            <xs:extension base="xs:string">
                <xs:attribute name="src" type="srcType" />
            </xs:extension>
        </xs:simpleContent>
    </xs:complexType>
</xs:element>

在maxOccurs="unbounded"元素的规范中缺少1（或某些大于img的值，默认值）（假设XML实际上有多个{{1} img里面的元素，因为它是复数，我猜是这样的。）

XML Schema不会验证
