<p>This function needs to handle all messages to the path of the virtual object, when the SubPath option is specified. The service, path, interface and methos are all part of the <i>message</i>.

<p>This function needs to handle the introspection of the virtual object on <i>path</i>. It must return xml of the form:</p>
