incorrect warning: member with role "stop" does not match "railway=halt"

[aceman]

I have a railway relation with "public_transport:version=1" but I get validator warning of 'member with role "stop" does not match "highway=bus_stop

railway=station

railway=halt && railway=tram_stop"' on a stop node that is "railway=halt". The warning itself says railway=halt is a correct possibility. So what is wrong with the validator check? Is the '&&' operator actually correct? Shouldn't it be '

' ? If I change the node to "railway=station" the warning does away.
