Summary:

This document is written very clear and comprehensive. It is Ready. 
One single question remains open, it is minor.

Major issues: None

Minor issues:

Section 3.1.1, second paragraph states ".. every node along the path must be able to identify unambiguously the colored packets". 

I think the scheme should work even if some intermediate nodes don't support the proposed scheme. If every node supports the scheme, using Link based method, there shouldn't be any disorder of packets. Correct?

Section 3.1.1 last paragraph also states that the "how to choose the marking field ... is out of the scope". Besides the DSCP field, what other options there could be? Just curious. 

Nits/editorial comments:

Thanks, Linda Dunbar
