Bruce Bartell commented on ENERGYINTEROP-496:
---------------------------------------------

To clarify what is in the proposal: The first level within EventBaseline is a choice of xcal:vcalendar or eitc:vcalendar, and power:powerReal. So presumeably this means that powerReal is applicable to the entire EventBaseline.
But, eitc:vcalendar contains eitc:ArrayofElements which contains a choice of one, which is eitc:interval
eitc:interval contains eventBaselineDescription which is an extension of the eitc:eventDescriptionBase substitution group.
eventBaselineDescription contains power:EnergyReal and a quantity.  eitc:interval has a duration.

So it looks like we can have the default be PowerReal, which is probably what the aggregators are going want. And  can override at the interval level to be Energy for what is may the settlement view of  a baseline. Assuming this meets the override rules.

This introduces 2 different problems:
eitc:interval only has a duration. The start is in the other choice at that level. The schema comment for eventBaseline says "xs:appinfo>eventBaseline should be paired with eventBaselineDescription types in the gluons and intervals</xs:appinfo>". What does "paired" refer to? Is there a missing element? I see a dtstart in xcal:properties of xcal:vcalendar, but this is in a choice so I can't get to both places.

Extending eventBaseLineDescription makes signalInformationBase available in this element. I'm not sure what I would with a value for signalDelta if I got one in a baseline.

> Baseline calculations use either Power (W) or Energy (Wh) depending on whose program it is. 
> PJM uses an average kW at one-minute interavals. California Edison uses KWh per hour. NYISO  uses MWh per hour.
