I think it's better now. Thank you for your kindly clarifying.

the RA represents a partition of the data plane and is used as the 
representation of the data plane within the control plane, in the
next revision will include a statement on this since this may be
where the mis-understanding comes from, wrt to relationship with
the RC, the text will be clarified from:

   " - A RA MAY support different routing protocols. There SHOULD NOT be
       any dependencies on the different routing protocols used.
     - For a RA, the cluster of RCs is referred to as a routing domain.
       The routing information exchanged between routing domains (i.e.
       inter-domain) is independent of both the intra-domain routing
       protocol and the intra-domain control distribution choice(s), e.g.
       centralized, fully distributed."

to:

    "- For a RA, the cluster of RCs is referred to as a routing (control)
       domain. The RC MAY support more than one routing protocol. There
       SHOULD NOT be any dependencies on the different routing protocols
       used.
     - The routing information exchanged between routing domains (i.e.
       inter-domain) is independent of both the intra-domain routing
       protocol and the intra-domain control distribution choice(s), e.g.
       centralized, fully distributed."

well hope this clarifies,
- dimitri.
