Gerald Gray commented on EMIX-409:
----------------------------------
I see two challenges, 1) using a CIM reference if what we are doing is not CIM-ish. If it is CIM-ish we might use the appropriate reference which I "think" is:
IEC 61970-301 Energy Management System Application Program Interface (EMS-API) — Part 301: Common Information Model (CIM) Base
2) Per your question 2, I created an example XSD that contains curve, curvedata, and curvestyle enum below:
Feel free to copy and paste into your XML viewer of choice. Provided as an example of the CIM curve related classes to inform the discussion:

> 681 technical "ramp rate curve"? Where exactly is this defined? What is the name of the document? What is the name of the CIM class it inherits from?
> 703 technical "mrid"? I believe IEC TC57 WG13 has developed a document to define the mrid. You must either define what you mean by "mrid" and the rules associated with the use of it, or cite someone else's document that does this for you. There are very specific rules for its construction and use that need to be followed.
