The (sus2nd) is enharmonic with the (9th) only difference is the sus2 comes before the 7th is added. OR an octave appart :) I've been told that I'm wrong ,this maybe true. I made acouple of adjustments. the reason I belive this to be true is that I have seen chords with a (sus2) & chords with a (mi3). soi base my opinion on that . The sataement "there is no aug2" is proably too restrictive.
