Adding validation to a web service?

[DomoChan]

I have some methods which I would like to be validated at the web
service level. for instance, if I have a function IsNumberFive( int
value ); I want it to be embedded in the wsdl file to check for
value=5. I dont want to do this programatically. I heard there was a
validation mechinism for wsdl but I dont know what it is or how to use
it?

Thanks,

To post an update, I found this, which looks like there's nothing
built into .net as of version 2.0 http://www.owasp.org/index.php/.NET_Web_Service_Validation#Downloading
But perhaps this is dated compared to other existing technologies?
