\framed[frame=off,align=flushleft,width=\textwidth]{\phrasetext{metamodelexplanation}}

but the text inside the frame is typeset with indentation.

I tried \setupindenting both before and after \starttext, (none,no,never) but that doesn’t work. 

How do I turn indenting off in all frameds with align=flushleft or otherwise *everywhere*?
