[pim] draft-ietf-pim-zeroconf-mcast-addr-alloc-ps issue(s)

Just doing RTGDIR review of draft-ietf-pim-ipv6-zeroconf-assignment
and stumbling across the following in subject draft:

So far, the whole justification of the draft, avoidance of collisions
at link-layer is only written out in the explanatory text, but not
mentioned in the requirements:

[REQ-1] Unique Address Assignment: Use of the solution SHALL
result in a unique address being assigned to the multicast group.

replace for example:

[REQ-1] Unique Address Assignment: Use of the solution SHALL
result in an assignment of an IPv4 and/or IPv6 multicast address
that is unique, and whose link-layer address is also unique.

also:

[REQ-8] Collision Detection and Resolution: The solution SHALL
include mechanisms to detect and resolve multicast address
collisions.

maybe:

[REQ-8] Collision Detection and Resolution: The solution SHALL
include mechanisms to detect and resolve multicast address
collisions including collisions at the link-layer.

Haven't thought about the right wording in too much detail. But
its IMHO front and center to ensure the link layer collision
avoidance is explicitly mentioned in those requirements.

more minor:

I can not find an explanation as to what CONS-6 would be good for.
Some example would be good. Is this for example about enumeration
of all used addresses for network management purposes ? Then maybe
rephrase accordingly "Third-party (network management) application
SHOULD be capable to determine all currently used addresses".

CONS-7 is also unclear. Again, think of explicit goal and try to
rephrase accordingly.

Cheers
