How to validate number of renderings on item

How do i perform validation on number of rendering applied on any item.
i want to restrict rendering with placeholder say 'xyz' to 3 i.e that rendering with placeholder 'xyz' should not exceed 3 times on item.
e.g. if i apply rendering 'rend_card' more than 3 times on item. then it should show me validation error.
