Subject: RE: RM Group Definitions

Normally, when a party needs to know whether a message was received before
sending another, they use a request-response protocol at the business

I agree. It isn't clear to me where the notion of BP-level
or application-level grouping came from as I haven't had
an opportunity to read ALL of the messages sent during my
vacation, but this seems to me to be something we should
steer well clear of.
