In the Introduction sections, both the EI and EMIX specs say they each provide
... a set of messages to communicate price ... . 1
To have them both say they provide the same thing blurs the line of where EI stops and EMIX starts.
The terminology could use some clarification/definition. I'd propose something more along the lines of EMIX providing an XML vocabulary for communication of Price and Product information , or something similar, to distinguish it from getting into the messaging / communication services context of EI.
Does anyone else have suggestions/opinions on this? I think we have several issues around clarification of EI/EMIX boundaries so if that is in process perhaps this can be added to the list. I don't know how those are being tracked since they're between TCs.
