        At the very least, a client SHOULD ensure that the <code>version</code> member 
        appears first and the <code>params</code> member last. 
        An example how this can be an advantage is 
        where a client tries to invoke a procedure that does not exist on the target service. The server can then skip to the end and issue an error as soon as it reads
        the value of the <code>method</code> member and finds it to be in error.</p>
