EI/EMIX spec wording clarification request

[Anne Hendry <ahendry@pacbell.net>]

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.
