Validating parameters passed to Web Service

[Jackie W]

Has .NET any XML-based validation framework or tool classes to validate
parameters passed to an Web Service?

I need only couple of types validation
- is parameter passed to Web Service method empty
- does parameter belong to certain value set which is mentioned
earlier somewhere in XML files.
So, very simple validation.

Cheers!

Why not validate these within the WS method?
