Minor Line 171 states:
"This document defines a set of messages to communicate Price and Product definition ..."
This closely resembles line 10 in the EI spec (wd22 pdf):
"Energy Interop defines messages to communicate price ..."
I thought EMIX was defining the payload,
more along the lines of how it's stated in Line 331:
EMIX defines the information for use in messages that convey this
[Price and product] actionable information.
and Line 375:
EMIX is not concerned with the processes whereby an actor provides
the products and resources it describes. EMIX is an information model
that assumes conveyance within a service-based environment.
So this first sentence confuses scope.
