I know about that too, the KnownType is applied to types that the DataContractSerializer (not the XmlSerializer) must be aware of before it can serialize the type (you enlist the type to the serializer). Thanks.
For a general purpose serialization it can make sense to support arbitrary types, but WCF is a communication technology that warrants contracts including and especially web-services that usually require full contract to be expressed in WSDL in order to be cross-platform.
