[RJ] I was referring to Table 1 in Section 4.1 but I guess the table
in Section 9.4 is the same. But yes, these are indeed ND (E)ARO status
codes. Sorry for the confusion.

[RJ] I think the 'A' bit in section 7 which says that the RPL status
is originated from ND EARO is the central point here. ND is using
RPL's base object Status field to propagate its status.
RPL Status field is getting used as of now in, DAO-ACK [RFC6550] and
DCO [efficient-route-invalidation draft].
My reason to start this discussion was to clarify the intersection
between ND/RPL to WG and the conclusion of this discussion will lead
to another mail wherein I would like to propose final changes to DCO's
Moved status value (which is currently 130).
