Re: [Roll] Published draft-ietf-roll-unaware-leaves-17.txt

Thanks Pascal for the updates,

As per our discussion and your summary for the published -17 draft, we
should be mandating the use of Updated Target Option. However, I don't see
any clear text suggesting so in the draft. Am I missing something? The
draft mentions the use of Updated Target Option only in response to the "P"
flag. There are sections (for e.g., Section 10.2.2) which still refer to
RPL Target Option and not the updated one. There is text (section 6) which
still suggests that keep-alive EDAR/EDAC can be sent from 6LR.

Other comments:
1. Section 1: "either as a collection tree or with routing back." -> I
don't understand what "routing back" means here.
2. Section 10.2.2
      a. Refers to RPL Target Option and not the Updated Target Option
      b. ROVR field addition to the Updated Target Option must be specified
in this section
      c. As per 8505 TID is optional. However the draft assumes that TID is
always copied from the EARO to the Path Sequence of DAO.
3. Section 9. Should we mention that the Option Length MUST be >= 18 if the
"F" flag is set?

Nits:
* "Direction-Oriented Directed Acyclic Graphs" ->  It should be
Destination-Oriented
* an RAN injects -> a RAN injects
* "even when the DODAG is operated in Storing Mode DODAGs" -> remove DODAGs.
* "such a Ethernet" -> "such as Ethernet"
* "Sollicitation" -> "Solicitation" ... multiple places
* "set to 0 a prescribed by" -> "set to 0 as prescribed by"
* "For the refreshes of the registration, .." -> "For registration refresh,
.."
* "if the "I" field" -> "If the "I" field"
* "A RPL Root SHOULD set the "P" flag in the RPL configuration option" ->
"A RPL Root SHOULD set the "P" flag in the RPL DODAG Configuration Option"

Best,
Rahul
