Dear authors,

The document looks rather complete and comprehensive.

There are a few questions:
Do I understand correctly that contrary to RFC 4861, the neighbor cache is 
always empty in 6LN. If true, this remark may be added to Registration term of 
section 2.
>From that do I deduce correctly that access to the link for link-local 
>addresses (LLA) involves extracting the MAC address from the LLA.

MUST a 6LBR be present in an isolated LOWPAN? (6LBR text in section 2 seems to 
imply this)
Assuming an isolated LOWPAN without 6LR or 6LBR, then there will be no answer 
to the RS message, but the node can continue sending messages to LLA, where the 
MAC address is again extracted from the LLA. Is that correct?
