How can I fix the web link proxy generated by Visual Studio for processing jagged arrays?

Question

There seems to be a known bug in wsdl.exe, a tool that Visual Studio uses to create web service proxies. Using some XSD schemas, the tool will generate classes that cannot be deserialized from XML.

As far as I understand, this is unacceptable, but I do not know how to fix it.

I will tell you in detail about my case, I hope someone can help me.

Scheme

<!-- return type from the service operation -->
<xs:complexType name="listAssetsQueryResults">
    <xs:sequence>
        <xs:element name="assets" type="tns:asset" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
</xs:complexType>

<!-- a sequence of attributes -->
<xs:complexType name="asset">
    <xs:sequence>
        <xs:element name="attributes" type="tns:multiValuedAttribute" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
</xs:complexType>

<xs:complexType name="multiValuedAttribute">
    <!-- not relevant-->
</xs:complexType>

Web service XML response

A typical answer according to this scheme is as follows:

<assets-query-result>
    <assets>
        <attributes>
            <name>Keywords</name>
            <values>Desert</values>
        </attributes>
        <attributes>
            <name>Filename</name>
            <values>Desert.jpg</values>
        </attributes>
    </assets>
    <assets>...</assets>
    <assets>...</assets>
</assets-query-result>

Using types in code

I expected that I could use CLR types as follows:

result.assets[0].attributes[0].name

Instead, the generated type for the result is as follows:

[SerializableAttribute()]
public partial class listAssetsQueryResults {
    private multiValuedAttribute[][] assetsField;

    [XmlArrayAttribute(Form=XmlSchemaForm.Unqualified, IsNullable=true)]
    [XmlArrayItemAttribute("attributes", typeof(multiValuedAttribute), Form=XmlSchemaForm.Unqualified)]
    public multiValuedAttribute[][] assets {
        get { return this.assetsField; }
        set { this.assetsField = value; }
    }
}

This does not even allow the serialization assembly to be generated!
