Re: [Dime] Topic 2 of draft-ietf-dime-congestion-flow-attributes-00 - Use Cases

[Jouni Korhonen <[e-mail]>]

Brent,

I do agree with your conclusion that adding examples would be minimal 
incremental addition to what RFC5777 already has. Also, IMHO use cases 
for ECN should be rather well known. I see no reason to add text for 
"topic 2".
