Was this point addressed in 05?

>> Clarify bootstrapping and DAD for link-local or not How to inform duplicate address detection during link-local address formation

Section 11 talks about boot strapping and the formation of a
link-local address, but it doesn't talk about DAD for the LL address.

Section 5 has this bullet:

   o  Address Resolution and DAD uses the registered addresses instead
      of multicast Neighbor Solicitation messages for non-link-local
      IPv6 addresses.

which seems to suggest DAD is used for link-local addresses, but it's
not really clear (and this is not an addition to 05).

Assuming the intent is to perform DAD for the link-local address, I
suggest Section 11 explains that explicitly.  It would also be better
if that point is clarified in Section 8.  And, this point of Section 2
may also have to be updated:

      Remove the use of multicast for DAD and Address Resolution (no
      multicast NS messages), and remove periodic multicast RAs.  Some

so it's clear that DAD is still needed for link-local addresses.
