Issue

Double VAr DataObject inside ZHAF LNClass

Table 117 – Data objects of ZHAF
- VAr, MV, Phase Reactive Power (Q), O / O
- VAr, MV, inherited from: ReactiveComponentInterfaceLN, O / O

The same in the IEC_61850-90-14_2020A3.nsd:
- <LNClass name="ZHAF" ... base="ReactiveComponentInterfaceLN">
<DataObject name="VAr" type="MV" presCond="O" dsPresCond="O"/> - <AbstractLNClass name="ReactiveComponentInterfaceLN"
base="EquipmentInterfaceLN">
<DataObject name="VAr" type="MV" .. presCond="O" dsPresCond="O"/>

Proposal

Remove VAr DO from ZHAF LNClass.
The ZHAF class derives this VAr DataObject from ReactiveComponentInterfaceLN
