Using the following categories

  BP - Business Process Level i.e. the consumer of ebXML TRP
  TPRC - ebXML TP&R Core functionality
  TPRM - ebXML TP&R Reliable Messaging

Here is how I would characterize your list. Again IMO.

>- Successfully passed authentication/access control

Are you referring to, how two peer ebXML transport providers mutually 
authenticate or are you referring to how a Business Process establishes 
its' identity to a local ebXML transport provider? I believe the latter is 
a private matter and out of scope. I'm not sure whether we will tackle the 
latter in ebXML. Thoughts ?

>- Successfully sent the bits to the other end

TPRM. I think there are lots of details in this one which we should expand.

TPRC. Need to spell this out - preseumably in the Service definition document.

BP. I would not get bogged down in this one within TR&P.
