Property "translate"

Folks,

My CSS got an error message "CSS; translate: Property translate doesn't exist."

As you surely know, it does exist. Perhaps you could update the validator to accept it. CanIUse says browser support has been near universal for a couple of years now, though Dreamweaver still doesn't know what to do with it either. . 

(Got the same message when I tried rotate. Didn't try other transformation properties, such as scale, but I suspect I would have for them too.)

Thanks,
