254 : This introduction clearly positions the EMIX information model as focused on price and product definition and messaging for energy.
266: For the first time we introduce the term "resource" as in "energy and resource markets" I see no clear purpose and possible confusion in using the term resource unless we are to better define the non-energy product emix one day may address. I recommend droping the term "resource" here. I think we are talking about products as our more general term and then energy, then electricity and then AC power specifically..
278 Here we introduce the term "commodity" In common language this is no problem but to be more consistent we could use the term "product" instead.
308: this line introduces the concept of service - in general conversation I think there is no confusion, but I think we should stick to the term product which we can define elsewhere to include services if that is what we mean.
352 Change In EMIX, the product definition, in the form of a Resource (described below) is associated with an entire WS-Calendar Sequence or Partition.

to In EMIX, the product definition (described below) is associated with an entire WS-Calendar Sequence or Partition.

356 2.4.2.1 Change Resource Model to Product Model and make the rest of the document to use only Product and not Resource.

Since this a global change I will wait for feedback before suggesting changes to implement this suggestion.
