[API] Mistake on section 4.3.2.1

Hi,

On the current editor's draft there is a mistake [1] :

public PropertyValues getPropertyValues(Evidence evidence)
       throws NameException;

getPropertyValues should not raise NameException as it retrieves all known properties in all vocabularies.

If would be good if it could be fixed before the PR publication

Best Regards
