Since this draft is mercifully short, I did a quick review.

Notes:

- Pointers to documentation on how browsers are expected to be able to 
set QCI and WiFI markings would be a good addition. Compared to those, 
DSCP codepoint setting is well understood.

- I find it good that these 3 mechanisms are the only ones considered in 
the draft. I'm making the leap of faith that we intend to state that an 
implementation MUST implement DSCP codepoint marking, SHOULD implement 
QCI and WiFI markings when attached to appropriate interfaces, and that 
no other mechanism is going to get a MUST or SHOULD recommendation from 
the WG. If I'm right, can we make that explicit?

- The restriction to 3 levels of priority seems to me like a reasonable 
simplification. Again, I want to make sure that this is an explicit and 
supported choice of the group.
