Serializing the Request

An implementation MUST look up the Proxy Table to get the Request URI, ServerTypeName, Transport, and Content-Type. If the Proxy Table does not contain the Proxy, then the higher layer MUST be notified of the error. An instance of Method Signature MAY be constructed from the Remoting Types of the Arguments of the Remote Method that is being invoked.<48>

The Server Type name, Remote Method name, Method Signature, Input Arguments and CallContext MUST be serialized into message content. The serialization format of the message content is specified by the Content-Type value, specified as follows.
