Question : WS-Security and WSDL

Is there any way to define your WS-Security requirements in WSDL?

I have a service that requires a Username token, a MessageSignature, and EncryptedData.  How should the service consumer know this, if not for WSDL?  

References would be helpful.. :)

Thanks.

(Specifically, I'm writing this web service in C#, .NET Framework 1.1, WSE 2.0)

Answer : WS-Security and WSDL

U can have a SoapExtension Attribute in the Header. Then u can use the SoapHeaderAttribute to specify the tokens. These SoapHeaderAttributes represent a property that can be set and also retrieved.

[SoapExtension]
[SoapHeaderAttribute("UserProfile", Direction=SoapHeaderDirection.In)]
[SoapHeaderAttribute("MessageProfile", Direction=SoapHeaderDirection.InOut)]
[SoapHeaderAttribute("DataClass", Direction=SoapHeaderDirection.InOut)]

Then u can have three classe called UserProfile,MessageProfile and DataClass

MessageProfile will have a property called MessageSignature
UserProfile can have a property called Username  
DataClass can have a property called EncryptedData.

Or u can have all the three properties in the same class
