editorial comments on draft-ietf-v6ops-nap-06

gentlemen--

My attention was recently drawn to [draft-ietf-v6ops-nap-06], and I  
have found what I think are some easily corrected editorial problems,  
which I hope you will consider making when the AUTH48 event happens.

The document is Informational, not Best Current Practice, so I'm  
concerned about the possibility that excerpts which appear to make  
recommendations for implementers could be quoted out of context  
inappropriately.  I scanned the text for the word "should" and came  
up with a few places where that seems to be an easily corrected error.

In section 4.1: "A basic IPv6 router should have a default  
configuration to advertise inside the site a locally generated random  
ULA prefix, independently from the state of any external  
connectivity."  Also: "With external connectivity the simple gateway  
should use DHCP-PD to acquire a routing prefix from the service  
provider for use when connecting to the global Internet."  Recommend  
replacing "should" with "may" in both cases here.

In section 4.2: "To implement simple security for IPv6 in, for  
example a DSL or Cable Modem connected home network, the broadband  
gateway/router should be equipped with stateful firewall  
capabilities.  These should provide a default configuration where  
incoming traffic is limited [...]."  Also, "There should also be an  
easy interface which allows users to create inbound  
'pinholes' [...]."  Recommend replacing "should" with "may" in all  
three of these cases.

Also in section 4.2: "Administrators and the designers of  
configuration interfaces for simple IPv6 firewalls need to provide a  
means of documenting the security caveats [...]" Recommend inserting  
"may" before the word "need" in this sentence.

In section 4.4: "In any case the approach should be limited to uses  
with substantially fewer than the maximum number of routes that the  
IGP can support [...]" and "Hosts should also listen to the IGP for  
duplicate use [...]" Recommend replacing "should" with "may" here.

Thank you for your time and attention.
