Sentence:  It has been pointed out in another chapter of this study that this formula has the same character as the so-called <WSD>promulgatory</WSD> clauses used in statutes to testify that the statute has been issued in conformity with the Constitution; and that in treaties <WSD>promulgatory</WSD> clauses, that is to say, clauses that declare that the rules laid down in the treaty have been created by an agreement of states, are superfluous. 
Meaning of the word marked with <WSD> tags:  That proclaims; declaratory.
