keep-warm function
How the appliance holds its contents warm after heating — a token from KeepWarmModes (none / fixed / adjustable / timed). Answerable for any hot-beverage water-heater (the value is 'none' when there is no hold function), so it homes on WaterHeatingAppliance rather than on a single kind. Optional.
Keep-warm function is answered with one word chosen from the keep-warm modes list — the same word shared across every product that uses it.
It belongs to measurement — its measurable, physical facts.
