JavaFX Form Validation

Would it be possible to attach our own arbitrary pseudo classes to controls via code?

Eg. Button.setPseudoClass("highlighted")

That would then cover the error case and much more. Eg I might have 'error', 'warning', 'required', 'highlighted', etc. 

I do not know if the CSS engine will be able to handle this.
