[pntaw] FW: [rtcweb] Query/Comment on draft-ietf-rtcweb-use-cases-and-requirements-12

["Chenxin (Xin)" <[e-mail]>]

 I find it lost in rtcweb mailing list, so I forward it to pntaw list, I think the guys following this group will be interested in this change proposal. I do not like silence too and I hope the usecase and requirement could be published ASAP.

 The change proposal is related to the discussion on pntaw. Also ,I hope the words could be more accurate and the requirement could be clearer.

 So ,any ideas about it?

 To Magnus:
    What will happen if there is no response?

Best Regards,
     Xin

WG,

It has been quite some time since the WG last call ended and a new
revision was submitted. As Document Shepherd I want to push this
document to publication request.

Chenxin proposed below three different sets of changes to the document.
Does the WG support making these changes? Please indicate within the
next week if you support or want to reject these changes.

Thanks

Magnus
