Major Power.xsd:
In power:UnitEnergyPriceType "energyApparant" is mis-spelled; use "energyApparent" Likewise correct power:EnergyApparantType, power:energyApparant, power:PowerApparantType, powerApparant, and uses such as line 188, itemDescription. The documentation on line 183 is correct.
Documentation for ServiceLocationType is more extensive than for other emixInterface substitution group members. This makes the diagrams from XML spy lopsided (too much for ServiceLocation, too little for others).
90: power.xsd
Why is AggregatedPnode element name capitalized and no others in the substitution group? (meterAsset, pnode, serviceDeliveryPoint, ...)? Should be consistent.
