The definite description is "proper" if X applies to a unique individual or object.  For example: "the first person in space" and "the 42nd President of the United States of America", are proper.  The definite descriptions "the person in space" and "the Senator from Ohio" are "improper" because the noun phrase X applies to more than one thing, and the definite descriptions "the first man on Mars" and "the Senator from some Country" are "improper" because X applies to nothing.
