Hi all, We are currently exploring creating xeto specs for our steam heating control systems. We often need to distinguish between "Domestic HOT Water" quantities and "Domestic COLD Water" quantities as a matter of course. To that end, we have attempted to write a Xeto spec for a "Domestic Hot Water Temperature Sensor Point" :

DomesticHotWaterTemperature: NumberPoint {
    domestic
    hot
    point
    sensor
    temp
    water
}

However, when we attempt to use this spec to validate pre-existing point records in our database, we come across this error:

Slot pointSubject: Conflicting choice ph::Phenomenon: DomesticWater, HotWater

Is there a workaround, say building a DomesticHotWater pointSubject choice, that would allow us to use the spec written above?

Currently that is not allowed since we treat hot-water and domestic-water as an exclusive choice (the first for heating/process only purposes). That is probably something that needs to be discussed in Labs WG. I would image new/different tags is the suggestion to not create semantic confusions. I believe it was discussed years ago a bit, but with no outcome
