This very first sentence seems off to me as later in the charter it's
mentioned that no solutions are going to be directly in scope so will the
work actually provide this or just outline the challenges and point towards
solutions in DetNet/Manet/other WGs?  If no solutions will be in scope then
I suggest leading with the next 1-2 sentences mixed with the first as way
of introduction to RAW.

In terms of presentation of information the critical bit of info that RAW
will NOT work on solutions seems a bit buried here and this should be moved
towards the top.

Unnecessary suggest cutting previous sentence.

"these groups" meaning "these non-IETF groups"?
