Description

From tissue proposal:
"In the wind domain there can be multiple sensors for the same kind of measurement (e.g. wind speed) at the same altitude.
Following established modelling praxis in wind domain and OEM consensus
MMET instances in 61400-25 modells Sensor altitude (not measurement altitude) of metrological mast or a metrological installation on a turbine. As there shall be one instance of WMET per altitude in IEC 61400-25, OMulti is required for the stated DOs."

This topic has discussed many time but we hadn't come to a final proposal. Rather to have multiple instances of DO in MMET, we could have multiple instances of LN that represent the different sensors at the same altitude.
