/**
 * An AMF Message contains information about the actual individual

 * operation that is to be performed; a local (client) operation
 * to be invoked upon success; and, the data to be used in the
 * operation.
 * <p/>
 * This Message structure defines how a local client would
 * invoke a method/operation on a remote server. Additionally,
 * the response from the Server is structured identically.
