Re: [CCAMP] I-D Action: draft-ietf-ccamp-rwa-wson-encode-16.txt

[Greg Bernstein <[e-mail]>]

Hi Giovanni we updated the WSON encode draft back on September 5th to 
put the interface class encoding into the draft. This was in response to 
the question raised by Lou in a August 20th email.  Lou, Deborah and OIC 
draft authors do we need to change this back?
Please let us know ASAP as we are trying to get all the WSON drafts into 
last call and this seems to be the last outstanding issue.

Best Regards
Greg

This separation will probably allow finalizing the wson-info-model and wson-encoding separately from specific OIC content (so we'll collect most updated ITU references as already mentioned we still miss few of them.
