In a note which we received from W. Schachermayer he called attention to some confusionin his paper [S1], which he said was noticed by H. Buhler. Our reading of this note madeus unhappily aware that some related confusion occurred in our papers [Sm] and [FS].The purpose of the present note is to eliminate the latter confusion. We are grateful toSchachermayer for bringing the confusion to our attention. His original note, expanded,will be published as [S2].
