Magento - remove from validation text

Some of us may not want the validation advice that is given, and prefer to just use CSS styling.
Here is how to remove it:
in /js/prototype/validation.js

test : function(name, elm, useTitle) {
        var v = Validation.get(name);
        var prop = '__advice'+name.camelize();
        try {
        if(Validation.isVisible(elm) && !v.test($F(elm), elm)) {
            //if(!elm[prop]) {
            /*
                var advice = Validation.getAdvice(name, elm);
                if (advice == null) {
                    advice = this.createAdvice(name, elm, useTitle);
                }
                this.showAdvice(elm, advice, name);
            */
            //}
            elm[prop] = 1;
            elm.removeClassName('validation-passed');
            elm.addClassName('validation-failed');
            return false;
        } else {
            //var advice = Validation.getAdvice(name, elm);
            //this.hideAdvice(elm, advice);
            elm[prop] = '';
            elm.removeClassName('validation-failed');
            elm.addClassName('validation-passed');
            return true;
        }
        } catch(e) {
            throw(e)
        }
    },
