								Declares protected predicates and protected grammar rule non-terminals. A protected predicate can only be called from the object containing the directive or from an object that inherits the directive. A protected non-terminal can only be used as an argument in a < a  title = "Consult reference manual"  href = "../methods/phrase2.html" > < code > phrase/2< / code > < / a >  and < a  title = "Consult reference manual"  href = "../methods/phrase3.html" > < code > phrase/3< / code > < / a >  messages sent from the object containing the directive or from an object that inherits the directive.
