I note that this document still talks about isolation and about hard and 
soft isolation.  The discussion around the network slicing definitions 
seems to me to have made it clear that we do not know what this means in 
any sense other than in terms of meeting the SLOs.  And in particular, 
we do not know what hard or soft isolation means.

I would ask that all of the discussion of isolation be removed from this 
document.

Yours,
Joel
