Re: ask for advise about "draft-ke-policy-icmp-ext-00.txt"

Thank you for asking.

This document falls within the scope of work that has been and is being 
done in some combination of the MPLS, Traffic Engineering, and CCAMP 
working groups (I lose track of which working group is tackling which part 
of the problem.)

The Policy Framework working group was focused on providing information 
models (and sample data mapping of those information models) for IP 
activities.  As such, this material would not have been within scope for 
the working group.  Also, we are in the process of closing down the working 
group.

Yours,
Joel M. Halpern
