Any comments about the approach of draft-ietf-netmod-routing-cfg-09?

A route is defined there as an extensible container, and future modules (e.g., 
those defining data models for routing protocols) are expected to augment this 
container with new attributes. This augmentation is described in sec. 4.4.2 
(Defining New Routing Protocols), and and example is shown in Appendix B for 
RIP.

It means that the definion of route is not fixed but depends on the modules 
supported by the device. 

Thanks, Lada
