Speaking with Chair hat on:

Your message starts by suggesting that this work does not belong in this 
working group but then moves towards discussing a solution for work that 
belongs in this working group.

As the CALL FOR ADOPTION comes to a close, the chairs are leaning 
towards interpreting your message as agreement there is work that could 
be done.  Note that adopting the document does not guarantee that it 
will be published by this working group; that will be decided as part of 
the discussion and review.

Is this okay with you?  If not, please do take some time to clarify your 
position.

Thanks,

Antoin and Jim
