So let's look at these one by one:

I think this is pretty clearly Informational; it was also identified as such 
pre-London, so I don't think this is particularly controversial as 
Informational. 

(Not really relevant to the charter, but on this point as we discussed in the 
hallway in Toronto, I think the right way to do this is to solicit 
contributions from people in the community who have deep knowledge of certain 
transport protocols to specify these in terms of their behaviors in individual 
I-Ds or I-D sections, then to have an editor pull these together into a 
coherent whole.)

In my opinion, whether this is PS or Info comes down to two questions: (1) is 
there an interoperability reason to specify a set of services that 
must/should/may/must not be provided by end systems and (2) will there be 
normative references to it from future PS documents?

I don't really have an opinion here, though I think I'd lean toward PS just for 
the sake of future utility. Note that if this milestone is PS it will have to 
restate the salient points of each selected behavior / 
service-in-terms-of-behaviors from the first milestone in normative language. 
I'm okay with that too.

Cheers,

Brian
