Re: I-D Action:draft-ietf-nsis-nslp-auth-00.txt

Hi

a few comments to this ID:
1. some text is QoS-NSLP specific:
s2: Network elements verify the request
    and then process the resource reservation message based on admission
    policy.
--> reservation, admission are meaningful in QoS context, not 
necessarily for FW/NAT or others.

s3.1: ... to verify the resource reservation request.
--> again, resource reservation

2. AUTH_SESSION, AUTH SESSION
--> AUTH_SESSION (only)

3. Furthermore, session ID, MRI,
    and NSLP ID have to be included into the checksum, too, as specified
    in Section 3.2.6.
--> where is checksum field/calculation defined here?

4. what if a targeted authorizing entity cannot support the requested 
AUTH_ENT_ID sub-types? s.6 does not talk about this. In multi-hop 
signaling cases (not just end host - last hop), this might happen.
