Service xml serialization [XmlAttributeAttribute()] ignored

Question

Hi,

I have a WCF web service developed with VS2010 targeting .Net Framework 4 which utilizes a serialization class generated from a xsd schema using xsd.exe.

When I request the xsd from the service (http://localhost:59120/Service1.svc?xsd=xsd2) the element attributes are ignored. E.G. in the schema snippet below (<xs:element name="id"...>) should be an attribute (<xs:attribute name="id"...>).

XSD schema snippet

...
<xs:sequence>
<xs:element name="address" type="xs:string" nillable="true"/>
<xs:element name="emailId" type="xs:string" nillable="true"/>
<xs:element name="id" type="xs:string" nillable="true"/>
<xs:element name="items" type="tns:ArrayOfArrayOfOrdersCustomerItemsItem" nillable="true"/>
<xs:element name="name" type="xs:string" nillable="true"/>
</xs:sequence>
...
