To drive a Servo what Capabilities do i need from a board? #500

Hi, i wish to drive a Servo with Firmata, however im confused what capabilities should the board have to support this. Im writing a script to detect the board capabilities and determine if that board can or cant drive a servo.

at the moment im checking for both PWM and SERVO capability PWM (0x03) SERVO (0x04)

is this correct? or should i only check for SERVO capability? thanks.

It's been a while since I've dug in, but I believe SERVO works as a specialized super set of PWM and will be enough on it's own.
