Use XML attributes to specify another XML name or namespace...

[Web Developer]

I've written a ServiceDescriptionFormatExtension that is used by my custom
SoapExtensionReflector so that I can add an authorization header to each web
service in my environment. In order for the update to work, I need the
following header added to the input and output sections of each service
operation of the wsdl:

<soap:header message="s0:AddRequesterIdentityHeader"
part="RequesterIdentityHeader" use="literal" />

The error below occurs when I use the following attribute on my custom
ServiceDescriptionFormatExtension:
<XmlFormatExtension("header", "http://schemas.xmlsoap.org/wsdl/soap/",
GetType(OutputBinding), GetType(InputBinding))> _

Here's the error:
System.InvalidOperationException:
There was an error reflecting type
'System.Web.Services.Description.ServiceDescription'. --->
System.InvalidOperationException: There was an error reflecting property
'Bindings'. --->
System.InvalidOperationException: There was an error reflecting type

System.InvalidOperationException:
The XML element named 'header' from namespace
'http://schemas.xmlsoap.org/wsdl/soap/' references distinct types
System.Web.Services.Description.SoapHeaderBinding and (my custom
ServiceDescriptionFormatExtension class).
Use XML attributes to specify another XML name or namespace for the element
or types.

Is there another way to generate the soap:header entries in the wsdl? There
seems to be a namespace conflict when I try to add nodes from the
http://schemas.xmlsoap.org/wsdl/soap/ schema.

Thank you.
