I am new to JSF

Why is it not possible to display error message for more than one validator for a particular component using message component

Whereas it is possible by messages component ,but as per my application i have to display all the error messages on top of the form.

so i have to show the error messages of a component in different color from all other error messages ,when the mouse is overed on that particular component for this purpose i need the "for" and "id" attribute, which is not possible in messages component.
