I think the AMS introduced `\dotsb` to separate the content and the markup, since some publishers use the lower dots »…« and not the centered ones »⋯« between operators. So `\dotsb` could just be redefined. Additionally amsmath defines it and to be compatible ConTeXt could define it too. Aditya more or less wrote the same in here response. Thanks, Paul
