[NTG-context] How to rotate the caption of a table...

Hello everybody, in my project is a table which does not fit the width of the page. Hence I need to rotate it. Rotating the table is ok, but the caption is not rotated. My question is how can I instruct ConTeXt to rotate the caption and place it on the right side? My attempt: \setupcaption[table][location=right,orientation=90] \startplacetable [location=middle, reference=tab:papierformaten, title={Standaardformaten}] \rotate[rotation=90]{\externalfigure[Table1][type=buffer]} \stopplacetable Thank you for your support Willi
