To share to all people on the mailing list.
sorry for my late reply .
I checked on Github the issue #19 (Deleting alarm attributes from the modeling )
related to PureEthernetStructure
and the HybridMwStructure.
Nokia devices support
for G826 PM counters on xxStructure container (1+1 scenario).
For this reason all the attributes listed on the issue #19 cannot be removed.
