Summary of changes:
- Added context identifiers to support multiple prefixes for
compression. Similar to Carsten's I-D, but allows a single context to
be used across different address compression modes.
- UDP compression no longer provides option for eliding UDP checksum.
- ISA100_UDP compression defined which does allow elision of UDP
checksum.
- Used an available bit to split Traffic Class from Flow Label
compression.
- Added some more words around multicast address compression, saying
that a node MUST subscribe to both compressed and uncompressed forms
and MUST NOT subscribe to only one. This rule means that nodes cannot
subscribe to well-known addresses that are not well-known to 6lowpan.
Feedback/suggestions welcome.
Thanks.

successfuly submitted by Jonathan Hui and posted to the IETF
repository.

Revision: 01
Title: Compression Format for IPv6 Datagrams in 6LoWPAN Networks
Creation_date: 2008-07-28
WG ID: Independent Submission
Number_of_pages: 14
Abstract:
This document specifies an IPv6 header compression format for IPv6
packet delivery in 6LoWPAN networks. The compression format relies
on shared context to allow compression of arbitrary prefixes. This
document specifies compression of well-known multicast addresses and
a framework for compressing next headers. UDP compression is
specified within this framework.
