The fact that 3gpp/2 maintains a list with their desires makes these
desires no more than just desires; in no case requirements to NETLMM WG.
  These lists are _not_ Best Common Practice.  The relationship between
3gpp/2 and IETF is described in RFC3131 and RFC3113.  Both these RFCs
are  INFORMATIONAL, not Best Common Practice.

If one needs to find out a Best Common Practice between IETF and SDO,
one would check RFC4053 Procedures for Handling Liaison Statements To
and From IETF.  That expects existence of one or several Liaison
persons.  If we don't have that then we don't act as Best Common Practice.

Can we reply to these statements?

I completely agree, thanks for posting this.  But 'SDO' is not a taboo 
subject, we can discuss about it, and we have guidelines about how to 
deal with SDO interactions, documented RFCs.

Vidya, could you please say yes or no can we as NETLMM WG members send
feedback to SDO?  If yes then how?

I will offer my feedback here, with respect to the letter NETLMM WG
Chairs received from WiMax Forum.  Do you Vidya think that I have to get 
consensus in this WG on this letter before sending it to WiMax Forum? 
Can you send this letter to WiMax Forum?  Please state a way to go.

Thanks for the letter, this WG is very aware of the above drafts, 
because they have been posted in the IETF Internet Draft repository. 
The WG is also aware of the urgent needs.

1. Stages of a IETF document
In IETF terms, there are several stages of completion for a certain
document: individual proposal, WG item, LC in WG, LC in IETF, in IESG
(with its IESG stages), AUTH48 and finally RFC number (champagne).
Which of these levels of completion do you refer to when asking Q3 2007?
   For which draft of the two?  Because if you request RFC number in Q3
2007 I think it may not be feasible, because several reasons that I can
explain separately, if interest is.

2. Status of IETF documents once RFC
An RFC, once issued, follows a certain 'track': Standards Track, or
INFORMATIONAL, or EXPERIMENTAL, or Best Common Practice.  The decision
on which track to pursue a document is happening when the respective
draft becomes a WG item.  Do you have a preference for any of these
tracks?  It can be explained further about the status, if need is, and
its impact on the speed of standardization.

3. PMIPv6 Draft
When you made the suggestion of PMIPv4 and PMIPv6 drafts (listed above),
were you aware of the existence of another PMIPv6 draft?
ftp://ftp.rfc-editor.org/in-notes/internet-drafts/draft-singh-netlmm-protocol-02.txt
If yes, can you please explain why this draft does not make part of your 
suggestion?  Is there a technical issue with it?  Is it a timing aspect 
(draft was recently posted)?  Because at IETF there's consensus usually 
to have all candidate protocol options on the table before making 
selection, sometimes there are even RFCs written only for selection 
purposes.
