Modify 14.1.2 Applicability as follows: The AppliesTo attribute MAY be used to restrict a term to a list of model elements that the term may be applied to. If no list is supplied, the term is not intended to be restricted in its application. The list of elements may be extended in future versions of the vocabulary. As the intended usage may evolve over time, clients SHOULD be prepared for any term to be applied to any model element and SHOULD be prepared to handle unknown values within the AppliesTo attribute.
