Liaisons referred by this one LS on concerns on the deprecation of dispatch type in 6loWPAN and its header compression mechanism to roll
Body 
The IETF will not change the definitions of the code points specified in RFC
4944 and RFC 6282, as published in IANA registry "IPv6 Low Power Personal Area
Network Parameters"
<http://www.iana.org/assignments/_6lowpan-parameters/_6lowpan-parameters.xhtml>,
in such a way as to affect the ITU-T G.9903 (02/2014: Table 9-35 - Command
frame header identifier) and G.9905 (08/2013: Table 7-1 - Command ID used in
ADP layer and Table 7-1a - Message type) specifications.

The IETF 6lo working group offers to collaborate with ITU-T SG15 in
establishing a new registry maintained by IANA for the code points following
the ESC dispatch code. This new registry will be populated at the time of its
establishment with the Command ID values as already defined in G.9903 and
G.9905.

We welcome experts also active in SG15 to participate in our next meeting: IETF
6lo and ROLL Working Groups meeting, 1 - 6 November 2015, Yokohama
