Why are you basing your decision to use active low or high level of the Field ID signal upon the platform data? Doesn't it depend on the configuration of the connected device, and, possibly, an inverter between them? So, looks like it should be handled in exactly the same way as all other signals - negotiate with the connected device (sensor / decoder / ...) and apply platform-defined inverters if any?
