Thanks Thomas for your reply. I am still new to Batik and SVG so please bear with me and correct me if I say anything wrong.

Do you mean if I add transform with scale to specific groups, only those groups will be zoomed when user clicks ctrl+I for instance? Or do you mean I have to get each specific group individually and then call setAttribute with transform and scale as parameters on it?
