Hello all,

I just looked at draft-ietf-roll-useofrplinfo-41.txt and specifically the
diff.

I have the following comments:
- Section 4.3: "leaving the flags reserved for MOP value seven (7)".
Actually, there is no normative text later in the document (e.g., Section
11) that implements this. MOP 7 is indeed reserved (see following comment,
though), but not the flags for the MOP 7. I think this would not be a good
idea anyway, since it would be starting designing the protocol that uses
MOP 7.
- Section 11.3: "this document changes the allocation status of the Mode
of Operation
     (MOP) [ianamop] from Unassigned to Reserved.". I guess you mean "his
document changes the allocation status of the Mode of Operation (MOP)
[ianamop] value 7 from Unassigned to Reserved.", correct?
- Section 4.3 "to be limited to Mode-of-Operation (MOP) specific.". I
can't quite parse this sentence. Do you mean "to be limited to
Mode-of-Operation (MOP) specific values."? Or "to be Mode-of-Operation
(MOP) specific."?
- Section 8.2.1: "Having the RAL information about the RPL domain, it may
encapsulate". "It" does not refer to anything identifiable. Grammatically,
it would refer to "the flow", which does not quite make sense.

Best regards

Dominique
